+.SH NAME
+\fBineg\fP \- integer sign inversion
+.SH SYNOPSIS
+.nf
+.B #include <libmpu.h>
+.PP
+.BI "void ineg( mpu_int *" c ", mpu_int *" a ", int " nb " );
+.fi
+.SH DESCRIPTION
+The \fBineg()\fP function changes the sign of an integer (NEG) located at  the address \fBa\fP
+and places the result at the address \fBc\fP. The contents of the memory at address \fBa\fP are
+not changed, the previous memory contents at address \fBc\fP are lost. The \fBnb\fP parameter
+determines the size of the operands (in bytes), located at addresses \fBc\fP, \fBa\fP.
+.PP
+The function affects the flags \fBA\fP, \fBC\fP, \fBO\fP, \fBP\fP, \fBS\fP, \fBZ\fP, and \fBV\fP.
+.PP
+Flags \fBА\fP and \fBP\fP are set only when the size of operand \fBa\fP is one or
+two bytes (\fBnb\fP == 1 || \fBnb\fP == 2).
