 .Sh SYNOPSIS
 .In math.h
 .Ft double
 .Fn round "double x"
 .Ft float
 .Fn roundf "float x"
 .Sh DESCRIPTION
 The
 .Fn round
 and
 .Fn roundf
 functions return the nearest integral value to
 .Fa x ;
 if 
 .Fa x
 lies halfway between two integral values, then these
 functions return the integral value with the larger
 absolute value (i.e., they round away from zero).

 .Sh STANDARDS
 The
 .Fn round
 function conforms to
 .St -isoC-99 .
 .Sh HISTORY
 The
 .Fn round
 and
 .Fn roundf
 functions appeared in
 .Fx 5.3 .
