+ABS(3)                    Minix Programmer's Manual                     ABS(3)
+
+
+NAME
+     abs - integer absolute value
+
+SYNOPSIS
+     #include <stdlib.h>
+
+     int abs(int i)
+
+DESCRIPTION
+     Abs returns the absolute value of its integer operand.
+
+SEE ALSO
+     floor(3).
+
+BUGS
+     Applying the abs function to the most negative integer generates a result
+     which  is  the  most  negative integer.  That is, abs(0x80000000) returns
+     0x80000000 as a result on a machine with 32-bit ints.  Using  the  result
+     in unsigned computations is sound however.
