+\fBb\fP is not changed, the previous memory content at \fBc\fP is lost. The parameter
+\fBnb\fP defines the size of the operands (in bytes) located at addresses \fBc\fP,
+\fBa\fP, \fBb\fP.
+.PP
+The function affects the flags \fBC\fP, \fBO\fP, \fBP\fP, \fBS\fP, \fBZ\fP.
+.PP
+The \fBA\fP flag is undefined. The \fBP\fP flag is set only when the size of the of the

+.TH iatoi 3  "December 27, 2024" "libmpu" "LibMPU Programmer's Manual"
+.SH NAME
+\fBiatoi\fP, \fBiatoui\fP \- functions for converting ASCII string to integer number
+.SH SYNOPSIS
+.nf
+.B #include <libmpu.h>
+.PP
+.BI "void iatoi( mpu_int *" c ", __mpu_char8_t *" str ", int " nb " );
+.BI "void iatoui( mpu_int *" c ", __mpu_char8_t *" str ", int " nb " );
+.fi
+.SH DESCRIPTION
+The \fBiatoi()\fP, \fBiatoui()\fP functions are used to convert an ASCII string into numeric form.
+In the case of \fBiatoi()\fP function, the \fBstr\fP argument is considered as a pointer to a character
+array containing characters of a signed integer; in the case of \fBiatoui()\fP function, it is assumed
+that the string contains a representation of an unsigned integer type numeric constant.
+.PP
+Numeric constants in a string can be represented as binary, octal, hexadecimal, and decimal numbers.
+Binary numbers begin with the prefix \fB0b\fP or \fB0B\fP, for example, \fB0b1011\fP. The octal numbers
+must begin with '0' and contain digits from '0' through '7'. Hexadecimal constants begin with the prefix
+\fB0x\fP or \fB0X\fP and can contain characters from '0' to '7' and characters from 'a' to 'f' in any case.
+Decimal constants can contain characters from '0' to '9' but must not start with '0'. Before a number
+signs '+', '-' are allowed. If a string contains a binary, octal or hexadecimal constant, the sign
+is ignored.
+.PP
+The result is placed at \fBc\fP, and the parameter \fBnb\fP represents the size of the result \fBc\fP
+in bytes.
+.PP
+If the number represented in the \fBstr\fP string does not fit into the specified (\fBnb\fP) format, the
+overflow flag (\fBO\fP) is set.
+.PP
+The function affects the flags \fBA\fP, \fBC\fP, \fBO\fP, \fBP\fP, \fBS\fP, \fBZ\fP. Flags \fBA\fP, \fBC\fP
+flags are reset to 0. The flag \fBR\fP is not changed.

+.SH DESCRIPTION
+The \fBidiv()\fP function performs the unsigned division of the variable located at \fBnum\fP
+by the variable located at \fBden\fP. The result is placed at \fBquot\fP. The remainder of the
+division is placed at \fBrem\fP. The memory contents at addresses \fBnum\fP, \fBden\fP are not
+changed, the previous memory contents at addresses \fBquot\fP, \fBrem\fP are lost.
+The \fBnb\fP parameter determines the size of the operands (in bytes) located at the addresses
+\fBquot\fP, \fBrem\fP, \fBnum\fP, \fBden\fP.
+.PP
+The function affects the flags \fBA\fP, \fBC\fP, \fBO\fP, \fBP\fP, \fBS\fP, \fBZ\fP, \fBR\fP.
+.PP
+The \fBA\fP flag is reset to 0. The \fBP\fP flag is set only when the size of the \fBprod\fP
+operand is one or two bytes (\fBnb\fP == 1 || \fBnb\fP == 2). The \fBR\fP (major || remainder)
+flag is set when the remainder is obtained of the division.

+.TH iitoa 3  "December 27, 2024" "libmpu" "LibMPU Programmer's Manual"
+.SH NAME
+\fBiitoa\fP, \fBiuitoa\fP \- functions for converting an integer to an ASCII string
+.SH SYNOPSIS
+.nf
+.B #include <libmpu.h>
+.PP
+.BI "void iitoa( __mpu_char8_t *" str ", mpu_int *" a ", int " radix ", int " uf ", int " nb " );
+.BI "void iuitoa( __mpu_char8_t *" str ", mpu_int *" a ", int " radix ", int " uf ", int " nb " );
+.fi
+.SH DESCRIPTION
+The functions \fBiitoa()\fP, \fBiuitoa()\fP convert an integer variable located at \fBa\fP into
+a string constant. The base of the numerical system is selected according to the value of the
+parameter \fBradix\fP. Valid bases are presented in the header file \fBlibmpu.h\fP:
+.nf
+.sp
+#define RADIX_BIN  2
+#define RADIX_OCT  8
+#define RADIX_DEC 10
+#define RADIX_HEX 16
+.fi
+.sp
+If you select the base \fBRADIX_BIN\fP or \fBRADIX_HEX\fP, you can additionally select the prefix
+representation register with the parameter \fBuf\fP, the allowed values of which are:
+.nf
+.sp
+#define LOWERCASE  0
+#define UPPERCASE  1
+.fi
+.sp
+are also represented in the header file \fBlibmpu.h\fP.
+.PP
+The \fBnb\fP parameter specifies the size of the \fBa\fP variable in bytes.
+.PP
+The \fBiitoa()\fP, \fBiuitoa()\fP functions do not affect flags.
+.PP
+The size of memory allocated under the \fBstr\fP pointer must be sufficient to accommodate the resultant
+string constant.
+.PP
+The \fBiitoa()\fP function assumes that the \fBa\fP variable is a signed variable, and the \fBiuitoa()\fP
+function treats the argument as an unsigned integer. For example, an 8-bit binary integer \fB0b10000000\fP
+will be converted to the string "\-128" by the function \fBiitoa()\fP, while the function \fBiuitoa()\fP
+will output the positive number "128".
+.sp

+.BI "void iatoui( mpu_int *" c ", __mpu_char8_t *" str ", int " nb " );
+.fi
+.SH DESCRIPTION
+Функции \fBiatoi()\fP, \fBiatoui()\fP предназначены для приведения (конвертации) ASCII\-строки в числовой вид.
+В случае функции \fBiatoi()\fP арумент \fBstr\fP рассматривается как указатель на массив символов, содержащий
+символы знакового целого числа, в случае \fBiatoui()\fP подразумевается, что строка содержит представление
+беззнаковой числовой константы целого типа.
+.PP
+Числовые константы в строке могут быть представлены как двоичные, восьмеричные, шестнадцатеричные и десятичные
+числа. Двоичные числа начинаются с префикса \fB0b\fP или \fB0B\fP, например, \fB0b1011\fP. Восьмеричные числа
+должны начинаться с символа '0' и содержать цифры от '0' до '7'. Шестнацатеричные константы начинаются с префикса
+\fB0x\fP или \fB0X\fP и могут содержать символы от '0' до '7', а также символы от 'a' до 'f' в любом регистре.
+Десятичные константы могут содержать символы от '0' до '9', но не должны начинаться символом '0'. Перед числом
+допускаются знаки '+', '-'. Если в строке представлена двоичная, восьмеричная или шестнадцатеричная константа,
+то знак игнорируется.
+.PP
+Результат размещается по адресу \fBc\fP, а параметр \fBnb\fP представляет размер результата \fBc\fP в байтах.
+.PP
+Если число, представленное в строке \fBstr\fP, не умещается в заданный (\fBnb\fP) формат, то выставляется
+флаг переполнения (\fBO\fP).
+.PP
+Функция воздействует на флаги \fBA\fP, \fBC\fP, \fBO\fP, \fBP\fP, \fBS\fP, \fBZ\fP. Флаги \fBA\fP, \fBC\fP
+сбрасываются в 0. Флаг \fBR\fP не изменяется.

+.fi
+.SH DESCRIPTION
+Функции \fBiitoa()\fP, \fBiuitoa()\fP осуществляют преобразование целой переменной, расположенной
+по адресу \fBa\fP, в строковую константу. Основание системы счисления выбирается согласно значению
+параметра \fBradix\fP. Допустимые основания представлены в заголовочном файле \fBlibmpu.h\fP:
+.nf
+.sp
+#define RADIX_BIN  2
+#define RADIX_OCT  8
+#define RADIX_DEC 10
+#define RADIX_HEX 16
+.fi
+.sp
+Если выбрано основание \fBRADIX_BIN\fP или \fBRADIX_HEX\fP, то дополнительно можно выбрать регистр
+представления префикса с помощью параметра \fBuf\fP, допустимые значения которого:
+.nf
+.sp
+#define LOWERCASE  0
+#define UPPERCASE  1
+.fi
+.sp
+также представлены в заголовочном файле \fBlibmpu.h\fP.
+.PP
+Параметр \fBnb\fP определяет размер переменной \fBa\fP в байтах.
+.PP
+Функции \fBiitoa()\fP, \fBiuitoa()\fP не влияют на флаги.
+.PP
+Размер памяти, выделенной под указателем \fBstr\fP, должен быть достаточен для размещения результирующей
+строковой константы.
+.PP
+Функция \fBiitoa()\fP подразумевает, что переменная \fBa\fP является знаковой, а функция \fBiuitoa()\fP
+рассматривает аргумент \fBa\fP как беззнаковое целое число. Так, например, двоичное 8\-разрядное целое
+\fB0b10000000\fP функцией \fBiitoa()\fP будет переведено в строку "\-128", в то время как функция \fBiuitoa()\fP
+выведет положительное число "128".
