.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).
