Detailed Description

Function Documentation

d_isEqual()

template<typename T >

static constexpr bool d_isEqual ( const T &  v1, const T &  v2  )

inlinestaticconstexpr

Safely compare two floating point numbers. Returns true if they match.

d_isNotEqual()

template<typename T >

static constexpr bool d_isNotEqual ( const T &  v1, const T &  v2  )

inlinestaticconstexpr

Safely compare two floating point numbers. Returns true if they don't match.

d_isZero()

template<typename T >

static constexpr bool d_isZero ( const T &  value )

inlinestaticconstexpr

Safely check if a floating point number is zero.

d_isNotZero()

template<typename T >

static constexpr bool d_isNotZero ( const T &  value )

inlinestaticconstexpr

Safely check if a floating point number is not zero.

d_nextPowerOf2()

static uint32_t d_nextPowerOf2 ( uint32_t  size )

inlinestaticnoexcept

Get next power of 2.

d_roundToIntPositive()

template<typename T >

static constexpr int32_t d_roundToIntPositive ( const T &  value )

inlinestaticconstexpr

Round a floating point number to an integer. Fast operation for values known to be 0 or positive.

d_roundToUnsignedInt()

template<typename T >

static constexpr uint32_t d_roundToUnsignedInt ( const T &  value )

inlinestaticconstexpr

Round a floating point number to an unsigned integer. Fast operation for values known to be 0 or positive.

d_roundToIntNegative()

template<typename T >

static constexpr int32_t d_roundToIntNegative ( const T &  value )

inlinestaticconstexpr

Round a floating point number to an integer. Fast operation for values known to be 0 or negative.

d_roundToInt()

template<typename T >

static constexpr int32_t d_roundToInt ( const T &  value )

inlinestaticconstexpr

Round a floating point number to integer.
