.SH NAME
fmax, fmaxf, fmaxl \- determine maximum numeric value of two floating-point
numbers

.SH DESCRIPTION
.sp
.LP
These functions determine the maximum numeric value of their arguments. NaN
arguments are treated as missing data: if one argument is a NaN and the other
numeric, these functions choose the numeric value.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, these functions return the maximum numeric value of
their arguments.
.sp
.LP
If just one argument is a NaN, the other argument is returned.
.sp
.LP
If \fIx\fR and \fIy\fR are NaN, a NaN is returned.
.SH ERRORS
.sp
.LP
No errors are defined.
