.SH NAME
\fBitest\fP \- integer comparison
.SH SYNOPSIS

.PP
.BI "void icmp( mpu_int *" a ", mpu_int *" b ", int " nb " );

.SH DESCRIPTION
The \fBicmp()\fP function compares the values of \fBa\fP and \fBb\fP (actually performing the
a \- b operation). The contents of memory at \fBa\fP and \fBb\fP are not changed. The \fBnb\fP
parameter defines the size of the operands (in bytes) located at addresses \fBa\fP, \fBb\fP.
.PP
The function affects the flags \fBA\fP, \fBC\fP, \fBO\fP, \fBP\fP, \fBS\fP, \fBZ\fP.
.PP
Flags \fBА\fP and \fBP\fP are set only when the size of operands \fBa\fP, \fBb\fP is one or
two bytes (\fBnb\fP == 1 || \fBnb\fP == 2).
