Description

f32 and f64 already have the gamma function from libm, would it be possible to get erf, erfc as well ?

Edit: I can try to do it myself if that helps.

Research direction

Start by tracing the existing f32 and f64 gamma-function support and how it connects to libm. Determine where the erf and erfc entry points belong, then verify that both functions are exposed consistently for the two floating-point types and covered by the relevant checks.
