struct f32

Declaration

struct f32 { /* full declaration omitted */ };

Description

A 32-bit floating point type. This type can represent a wide range of decimal numbers, like 3.5, 27, -113.75, 0.0078125, 34359738368, 0, -1. So unlike integer types (such as `i32`), floating point types can represent non-integer numbers, too. Specifically, this type holds the same values as the `float` type specified by the C++ standard. See the [namespace level documentation]($sus::num) for more.

Member Variables

public float primitive_value = float{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 float MIN_PRIMITIVE

Smallest finite primitive value.

public static const float MAX_PRIMITIVE

Largest finite primitive value.

public static const sus::num::f32 MIN

Smallest finite [`

public static const sus::num::f32 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::f32 EPSILON

Machine epsilon value for [`

public static const sus::num::f32 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::f32 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::f32 INFINITY

Infinity.

public static const sus::num::f32 NEG_INFINITY

Negative infinity.
