From: Ian Romanick Date: Mon, 4 Jun 2012 17:20:36 +0000 (-0700) Subject: glsl: Fix pi/2 constant in acos built-in function X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4bfdc8313592ec8a8794d6b7bc33a5c44df34ed4;p=mesa.git glsl: Fix pi/2 constant in acos built-in function In single precision, 1.5707963 becomes 1.5707962513 which is too small. However, 1.5707964 becomes 1.5707963705 which is just right. The value 1.5707964 is already used in asin.ir. NOTE: This is a candidate for stable release branches.
