Description

While working with wrappers of the SDL3 library I discovered
that passing/return of REAL argument does not work as expected
on Linux 64bit platform:

uname -a
Linux archlinux 6.18.9-arch1-2 #1 SMP PREEMPT_DYNAMIC Mon, 09 Feb 2026 17:16:33 +0000 x86_64 GNU/Linux

Windows 10 64bit was also tested with same result.

Attached files with a simple tests where the sin function
does not pass/return the correct values.

Sorry, generating wrappers for functions with floating-point parameters is not supported at the moment. You have to resort to writing wrapper functions manually. Thanks for reporting and sorry for the inconveniences.
