Constant RADIX 

pub const RADIX: u32 = f64::RADIX; // 2u32

👎Deprecating in a future version:

replaced by the RADIX associated constant on f64

The radix or base of the internal representation of f64. Use f64::RADIX instead.

Examples

// deprecated way
let r = std::f64::RADIX;

// intended way
let r = f64::RADIX;
