.Sh SYNOPSIS
.In stdlib.h
.Ft int
.Fn abs "int j"
.Fn abs "int x"
.Ft long int
.Fn labs "long int x"
.Ft long long int
.Fn llabs "long long int x"
.In inttypes.h
.Ft intmax_t
.Fn imaxabs "intmax_t x"
.Sh DESCRIPTION
The
.Fn abs
function
computes
the absolute value of the integer
.Ar j .
.Sh RETURN VALUES

.Sh STANDARDS
The
.Fn abs
function conforms to
.St -ansiC .
The described functions conform to
.St -isoC-99 .
.Sh BUGS
The absolute value of the most negative integer remains negative.
