struct f64

Declaration

struct f64 { /* full declaration omitted */ };

Description

A 64-bit floating point type. This type is very similar to [`f32`]($sus::num::f32), but has increased precision by using twice as many bits. Specifically, this type holds the same values as the `double` type specified by the C++ standard. See the [namespace level documentation]($sus::num) for more.

Member Variables

public double primitive_value = double{0.}

The inner primitive value. Prefer to cast to the desired primitive type, such as with `float{n}` for a numeric value `n`.

public static const double MIN_PRIMITIVE

Smallest finite primitive value.

public static const double MAX_PRIMITIVE

Largest finite primitive value.

public static const sus::num::f64 MIN

Smallest finite [`

public static const sus::num::f64 MAX

Largest finite [`

public static const sus::num::u32 RADIX

The radix or base of the internal representation of [`

public static const sus::num::u32 MANTISSA_DIGITS

Approximate number of significant digits in base 2.

public static const sus::num::u32 DIGITS

Approximate number of significant digits in base 10.

public static const sus::num::f64 EPSILON

Machine epsilon value for [`

public static const sus::num::f64 MIN_POSITIVE

Smallest positive normal [`

public static const sus::num::i32 MIN_EXP

One greater than the minimum possible normal power of 2 exponent.

public static const sus::num::i32 MAX_EXP

Maximum possible power of 2 exponent.

public static const sus::num::i32 MIN_10_EXP

Minimum possible normal power of 10 exponent.

public static const sus::num::i32 MAX_10_EXP

Maximum possible power of 10 exponent.

public static const sus::num::f64 NAN

This value is not constexpr because the value can differ in a constexpr evaluation context from a runtime context, leading to bugs.

public static const sus::num::f64 INFINITY

Infinity.

public static const sus::num::f64 NEG_INFINITY

Negative infinity.
