https://bugs.winehq.org/show_bug.cgi?id=50429 --- Comment #10 from Zebediah Figura <z.figura12(a)gmail.com> --- Here are the tests I did: 32-bit msvcrt: Results match x87 version using fpatan exactly. Results are affected by setting x87 control word precision flags beforehand. 64-bit msvcrt: A different set of results. Also affected by setting x87 precision flags. 32-bit ucrtbase: A different set of results. Not affected by x87 precision flags. 64-bit ucrtbase: A different set of results. Not affected by x87 precision flags. 32-bit wine results do seem to perfectly match 32-bit ucrtbase results. I didn't test with any other value than in the logs attached, though. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
