.SH SYNOPSIS

#include <math.h>

double remainder(double \fIx\fP, double \fIy\fP);
.fi
.SH DESCRIPTION
This function returns the remainder of a division of \fIx\fP by \fIy\fP. More
formally, it computes which integer \fIn\fP is closest to the fraction 
\fIx\fP/\fIy\fP and returns \fIx\fP - \fIn\fP*\fIy\fP. An even value for 
\fIn\fP is preferred over an odd one if both are equally far away (that is, 
banker's rounding is applied). If \fIx\fP is infinite or \fIy\fP is zero, 
a NaN value is returned.
.SH "RETURN VALUE"
The function returns the remainder of a division of \fIx\fP by \fIy\fP.
