ftz::ftz32 Struct Reference

Canonical binary32 word wrapper with named HLSL imports and exports. Ordinary aggregate casts/default storage do not normalize or initialize a value; use from_bits(), from_float() or zero(). Treat bits_ as implementation storage. More...

Public Member Functions
unsigned int	to_bits ()
	Exports the exact stored word without arithmetic.
float	to_float ()
	Exports stored bits as an ordinary HLSL float, leaving this value contract.
ftz32	operator+ (ftz32 rhs)
	Uses the selected shader FTZ policy for canonical operands.
ftz32	operator+ (float rhs)
	Imports a raw float operand before the operation.
ftz32	operator- (ftz32 rhs)
	Uses the selected shader FTZ policy for canonical operands.
ftz32	operator- (float rhs)
	Imports a raw float operand before the operation.
ftz32	operator* (ftz32 rhs)
	Uses the selected shader FTZ policy for canonical operands.
ftz32	operator* (float rhs)
	Imports a raw float operand before the operation.
ftz32	operator/ (ftz32 rhs)
	Uses the selected shader FTZ policy for canonical operands.
ftz32	operator/ (float rhs)
	Imports a raw float operand before the operation.
bool	operator< (ftz32 rhs)
	Compares canonical values; NaN is unordered and the two zero signs compare equal.
bool	operator> (ftz32 rhs)
	Compares canonical values; NaN is unordered and the two zero signs compare equal.
bool	operator== (ftz32 rhs)
	Compares canonical values; NaN is unordered and the two zero signs compare equal.
bool	operator!= (ftz32 rhs)
	Compares canonical values; NaN is unordered and the two zero signs compare equal.
bool	operator<= (ftz32 rhs)
	Compares canonical values; NaN is unordered and the two zero signs compare equal.
bool	operator>= (ftz32 rhs)
	Compares canonical values; NaN is unordered and the two zero signs compare equal.
bool	operator< (float rhs)
	Imports a raw float operand before the operation.
bool	operator> (float rhs)
	Imports a raw float operand before the operation.
bool	operator== (float rhs)
	Imports a raw float operand before the operation.
bool	operator!= (float rhs)
	Imports a raw float operand before the operation.
bool	operator<= (float rhs)
	Imports a raw float operand before the operation.
bool	operator>= (float rhs)
	Imports a raw float operand before the operation.

Static Public Member Functions
static ftz32	from_bits (unsigned int bits)
	Imports a binary32 word and replaces a subnormal magnitude with signed zero.
static ftz32	from_float (float value)
	Imports a float through its bits and normalizes subnormals.
static ftz32	unsafe_from_float32 (float value)
	Wraps bits unchanged; the caller must supply normal, signed zero, infinity or NaN.
static ftz32	zero ()
	Returns positive zero.

Detailed Description

Canonical binary32 word wrapper with named HLSL imports and exports. Ordinary aggregate casts/default storage do not normalize or initialize a value; use from_bits(), from_float() or zero(). Treat bits_ as implementation storage.
