# Math

# Description

The Math namespace contains tools for mathematical calculations, especially functionality related to floating-point precision handling.

# How to Use

// Using functions from the Math namespace
bool isZero = Math::IsZero(0.00000001f);
bool areEqual = Math::NearEqual(0.1f + 0.2f, 0.3f);

// Using Float_t type from Math namespace
Math::Float_t floatVal(3.14159f);

# Constants

# M_PI

#define M_PI 3.14159265358979323846f

Represents the value of pi (π).

float halfCircleRadians = M_PI; // Radian value of 180 degrees

# IsZero

bool IsZero(float A)

Checks if a floating-point number is zero (considering floating-point precision issues).

Parameter Type Description
A float The floating-point number to check
float value = 0.00000001f;
bool isZero = Math::IsZero(value);

# NearEqual

bool NearEqual(float A, float B, int maxUlpsDiff = 4)

Checks if two floating-point numbers are approximately equal, considering floating-point precision issues.

Parameter Type Description
A float First floating-point number
B float Second floating-point number
maxUlpsDiff int Maximum Units in Last Place difference, default is 4
float value1 = 0.1f + 0.2f;
float value2 = 0.3f;
bool areEqual = Math::NearEqual(value1, value2);

# Class:Float_t

A floating-point handling class that provides access to and manipulation of the internal components of floating-point numbers.

Math::Float_t floatVal(3.14159f);

# Float_t.Negative

bool Negative() const

Determines if the floating-point number is negative.

Math::Float_t floatVal(-3.14f);
bool isNegative = floatVal.Negative(); // Returns true

# Float_t.RawMantissa

int32_t RawMantissa() const

Gets the raw mantissa bits of the floating-point number.

Math::Float_t floatVal(3.14f);
int32_t mantissa = floatVal.RawMantissa();

# Float_t.RawExponent

int32_t RawExponent() const

Gets the raw exponent bits of the floating-point number.

Math::Float_t floatVal(3.14f);
int32_t exponent = floatVal.RawExponent();
