Constant core::f64::MANTISSA_DIGITS

pub const MANTISSA_DIGITS: u32 = f64::MANTISSA_DIGITS; // 0x0000_0035u32

👎 Deprecating in a future Rust version:

replaced by the MANTISSA_DIGITS associated constant on f64

This is supported on non-crate feature miri-test-libstd or test or doctest only.

Number of significant digits in base 2. Use f64::MANTISSA_DIGITS instead.

Examples

// deprecated way
let d = std::f64::MANTISSA_DIGITS;

// intended way
let d = f64::MANTISSA_DIGITS;
