Function std::intrinsics::fmaf64

pub unsafe extern "rust-intrinsic" fn fmaf64(
    a: f64, 
    b: f64, 
    c: f64
) -> f64

🔬 This is a nightly-only experimental API. (core_intrinsics)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Returns a * b + c for f64 values.

The stabilized version of this intrinsic is f64::mul_add
