From 3043b2f7fcf4471983c8d4472b17ccf9df1710c8 Mon Sep 17 00:00:00 2001 From: Micah Cochran Date: Sat, 28 May 2016 11:26:35 -0500 Subject: Change math constants, similar to PR #372. Use M_ namespace with the de facto standard M_PI and its ilk. Change names that are widely used in the project to be in the M_ namespace, so HALFPI becomes M_HALFPI. HALFPI is #defined as M_PI_2 (the defacto standard name). #defines _USE_MATH_DEFINES for MS Visual Studio (I didn't personally test this part, but Appveyor will not build otherwise). --- src/PJ_cc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/PJ_cc.c') diff --git a/src/PJ_cc.c b/src/PJ_cc.c index 475fbae4..34194418 100644 --- a/src/PJ_cc.c +++ b/src/PJ_cc.c @@ -7,7 +7,7 @@ PROJ_HEAD(cc, "Central Cylindrical") "\n\tCyl, Sph"; static XY s_forward (LP lp, PJ *P) { /* Spheroidal, forward */ XY xy = {0.0,0.0}; - if (fabs (fabs(lp.phi) - HALFPI) <= EPS10) F_ERROR; + if (fabs (fabs(lp.phi) - M_HALFPI) <= EPS10) F_ERROR; xy.x = lp.lam; xy.y = tan(lp.phi); return xy; -- cgit v1.2.3
