--- Comment #13 from Zebediah Figura z.figura12@gmail.com --- Created attachment 69080 --> https://bugs.winehq.org/attachment.cgi?id=69080 asin tests
Attached are my (much more crude) tests. I get different results between msvcrt and ucrtbase even on an up to date windows 10 (real metal) box. For example, msvcrt says asin(4.9649044871330261e-01) == 5.1955101354071775e-01, but ucrtbase has that ending in 1787. The msvcrt value also matches a stock windows 7 install running in a VM.
DLL versions are: win10 msvcrt: 7.0.19041.546 win10 ucrtbase: 10.0.19041.546 win7 msvcrt: 7.0.7600.16385
win10 processor is Intel Core i5-2400. Machine running the win7 VM is AMD FX 8350.
When running your test program on windows 10 I see a bunch of status word mismatches but no value mismatches.
