calculate the absolute value of a long integer
#include <stdlib.h> long int labs( long int j );
The labs() function returns the absolute value of its long-integer argument j.
the absolute value of its argument
#include <stdio.h> #include <stdlib.h> void main() { long x, y; x = -50000L; y = labs( x ); printf( "labs(%ld) = %ld\n", x, y ); }
produces the output:
labs(-50000) = 50000
