Module `f64`

Constants for the f64 double-precision floating point type.

[See also the f64 primitive type][f64].

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.
math Experimental implementations of floating point functions in core.

Constants

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