Bug 575 – wrong evaluation of (creal * 2 + 1i)

# cfloat test_f(cfloat a){ # return a * 2 + 1i; # } # cdouble test_d(cdouble a){ # return a * 2 + 1i; # } # creal test_r(creal a){ # return a * 2 + 1i; # } # # import std.stdio; # void main(){ # cfloat f = 1.0 + 2.0i; # writefln("f:\t%s", f * 2 + 1i); # writefln("test_f:\t%s", test_f(f)); # # cdouble d = 1.0 + 2.0i; # writefln("d:\t%s", d * 2 + 1i); # writefln("test_d:\t%s", test_d(d)); # # creal r = 1.0 + 2.0i; # writefln("r:\t%s", r * 2 + 1i); # writefln("test_r:\t%s", test_r(r)); # # writefln("direct:\t%s", (1.0 + 2.0i) * 2 + 1i); # } output: > f: 3+4i > test_f: 3+4i > d: 3+4i > test_d: 3+4i > r: 3+4i > test_r: 3+4i > direct: 2+5i expected output: > f: 2+5i > test_f: 2+5i > d: 2+5i > test_d: 2+5i > r: 2+5i > test_r: 2+5i > direct: 2+5i
