NAMEabs - integer absolute valueSYNOPSIS#include<stdlib.h>intabs(inti)DESCRIPTIONAbsreturns the absolute value of its integer operand.SEEALSOfloor(3).BUGSApplying theabsfunction 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.
