From e13a0b8b88b996be0364a374a32d60329a6b6552 Mon Sep 17 00:00:00 2001 From: Rajalakshmi Srinivasaraghavan Date: Sun, 12 Jun 2016 11:47:18 -0400 Subject: [PATCH] Add nextup and nextdown math functions TS 18661 adds nextup and nextdown functions alongside nextafter to provide support for float128 equivalent to it. This patch adds nextupl, nextup, nextupf, nextdownl, nextdown and nextdownf to libm before float128 support. The nextup functions return the next representable value in the direction of positive infinity and the nextdown functions return the next representable value in the direction of negative infinity.
