type c_float = f32;
Equivalent to C's float type.
This type will almost always be f32, which is guaranteed to be an IEEE-754 single-precision float in Rust. That said, the standard technically only guarantees that it be a floating-point number, and it may have less precision than f32 or not follow the IEEE-754 standard at all.
