From 0f1b23d08009b1254ae82712b5c976187d6c5729 Mon Sep 17 00:00:00 2001 From: kargl Date: Mon, 1 Sep 2014 16:24:25 +0000 Subject: Fix a tab that somehow became 8 spaces. Remove parentheses in a return statement to be consistent with the rest of the file. Rename sin_pi() in the float version to sin_pif(). Remove large comment that precedes sin_pif(). The comment duplicates a comment in e_lgamma_r.c where the algorithm is documented.
