.SH SYNOPSIS
|

.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.
