Constant std::f32::MANTISSA_DIGITS

pub const MANTISSA_DIGITS: u32 = f32::MANTISSA_DIGITS; // 0x0000_0018u32

👎 Deprecating in a future Rust version:

replaced by the MANTISSA_DIGITS associated constant on f32

Number of significant digits in base 2. Use f32::MANTISSA_DIGITS instead.

Examples

// deprecated way
let d = std::f32::MANTISSA_DIGITS;

// intended way
let d = f32::MANTISSA_DIGITS;
