/* FUNCTION <>---compute the absolute value of an long long integer. INDEX llabs SYNOPSIS #include long long llabs(long long <[j]>); DESCRIPTION The <> function computes the absolute value of the long long integer argument <[j]> (also called the magnitude of <[j]>). The similar function <> uses and returns <> rather than <> values. RETURNS A nonnegative long long integer. PORTABILITY <> is ISO 9899 (C99) compatable.
