# Module std::f64 1.0.0[−][src]

Constants specific to 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.
