Type Definition std::
os::1.1.0[−][src] raw:: c_double
type c_double = f64;
Equivalent to C’s
This type will almost always be
f64, which is guaranteed to be an IEEE-754 double-precision float in Rust. That said, the standard technically only guarantees that it be a floating-point number with at least the precision of a
float, and it may be
f32 or something entirely different from the IEEE-754 standard.
