# Constant std::f32::MANTISSA_DIGITS 1.0.0[−][src]

    pub const MANTISSA_DIGITS: u32 = f32::MANTISSA_DIGITS; // 0_x00_000_018u32

👎 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;
