# Module std::f64

Expand description

Constants for the `f64` double-precision floating point type.

See also the `f64` primitive type.

Mathematically significant numbers are provided in the `consts` sub-module.

For the constants defined directly in this module (as distinct from those defined in the `consts` sub-module), new code should instead use the associated constants defined directly on the `f64` type.

## Modules

- consts
  Basic mathematical constants.

## Constants

- DIGITS Deprecation planned
  Approximate number of significant digits in base 10. Use `f64::DIGITS` instead.
- EPSILON Deprecation planned
  Machine epsilon value for `f64`. Use `f64::EPSILON` instead.
- INFINITY Deprecation planned
  Infinity (∞). Use `f64::INFINITY` instead.
- MANTISSA_DIGITS Deprecation planned
  Number of significant digits in base 2. Use `f64::MANTISSA_DIGITS` instead.
- MAX Deprecation planned
  Largest finite `f64` value. Use `f64::MAX` instead.
- MAX_10_EXP Deprecation planned
  Maximum possible power of 10 exponent. Use `f64::MAX_10_EXP` instead.
- MAX_EXP Deprecation planned
  Maximum possible power of 2 exponent. Use `f64::MAX_EXP` instead.
- MIN Deprecation planned
  Smallest finite `f64` value. Use `f64::MIN` instead.
- MIN_10_EXP Deprecation planned
  Minimum possible normal power of 10 exponent. Use `f64::MIN_10_EXP` instead.
- MIN_EXP Deprecation planned
  One greater than the minimum possible normal power of 2 exponent. Use `f64::MIN_EXP` instead.
- MIN_POSITIVE Deprecation planned
  Smallest positive normal `f64` value. Use `f64::MIN_POSITIVE` instead.
- NAN Deprecation planned
  Not a Number (NaN). Use `f64::NAN` instead.
- NEG_INFINITY Deprecation planned
  Negative infinity (−∞). Use `f64::NEG_INFINITY` instead.
- RADIX Deprecation planned
  The radix or base of the internal representation of `f64`. Use `f64::RADIX` instead.
