Bug 18069 – Exponentiation operator ^^ not evaluable at compile time

Following code does not compile but should: ``` void main(string[] args) { import std.stdio; enum e = (1.0f / 255.0f) ^^ (1.0f / 2.2f); writeln("e = ", e); } ``` Error is: /usr/local/opt/dmd/include/dlang/dmd/std/math.d(440): Error: y.vu[4] is used before initialized /usr/local/opt/dmd/include/dlang/dmd/std/math.d(413): originally uninitialized here /usr/local/opt/dmd/include/dlang/dmd/std/math.d(4107): called from here: floorImpl(x) /usr/local/opt/dmd/include/dlang/dmd/std/math.d(2373): called from here: floor(x + 0.5L) /usr/local/opt/dmd/include/dlang/dmd/std/math.d(2110): called from here: exp2Impl(x) /usr/local/opt/dmd/include/dlang/dmd/std/math.d(6743): called from here: exp2(yl2x(x, y)) /usr/local/opt/dmd/include/dlang/dmd/std/math.d(6756): called from here: impl(cast(real)x, cast(real)y) test.d(5): called from here: pow(0.00392157, 0.454545) Forum thread: https://forum.dlang.org/thread/[email protected]
