Calculate the absolute value of a long integer
#include <stdlib.h> long labs( long j );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The labs() function returns the absolute value of its long-integer argument j.
The absolute value of j.
#include <stdio.h> #include <stdlib.h> int main( void ) { long x, y; x = -50000; y = labs( x ); printf( "labs( %d ) = %d\n", x, y ); return EXIT_SUCCESS; }
produces the output:
labs( -50000 ) = 50000
