```{index} single: remquo; POSIX function ``` ```{index} single: POSIX::remquo; Perl function ``` # remquo Floating-point remainder with partial quotient. ## Synopsis ```perl my ($rem, $quo) = POSIX::remquo($x, $y); ``` ## What you get back A two-element list: the IEEE remainder and the low bits of the quotient as an integer (typically at least three bits, enough for argument reduction of trigonometric functions). ## Differences from upstream Fully compatible with upstream POSIX.
