    pub type c_float = f32;

Expand description

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.
