Overview

Support for converting floating-point vectors to fixed-point vectors and fixed-point vectors to floating-point vectors.

These intrinsics can generate exceptions, for more information you can go here.

Note

These intrinsics do real conversions. No bit reinterpretation takes place.

Function Documentation

fix2float() [1/2]

v8float fix2float

(

v8int32

ivec

)

Fixed-point to Floating-point conversion without scaling.

Parameters

n	Integer input value

This is a vectorized version of fix2float(int n)

fix2float() [2/2]

v8float fix2float	(	v8int32	ivec,
		int	sft
	)

Fixed-point to Floating-point conversion with scaling.

Parameters

n	Integer input value
sft	Binary point of input value. Range [-32:31].

This is a vectorized version of fix2float(int n, int sft)

float2fix() [1/2]

v8int32 float2fix

(

v8float

v

)

Floating-point to Fixed-point conversion without scaling.

Parameters

n	Floating point input value

This is a vectorized version of float2fix(float n)

float2fix() [2/2]

v8int32 float2fix	(	v8float	v,
		int	sft
	)

Floating-point to Fixed-point conversion with scaling.

Parameters

n	Floating point input value
sft	Binary point of output value. Range [-32:31].

This is a vectorized version of float2fix(float n, int sft)

Note

If FLOAT2FIX_FAST is not defined, this is an alias to float2fix_safe(v8float v, int sft). Otherwise it is an alias to float2fix_fast(v8float v, int sft)
