Function Documentation

clamp()

float4 avir::clamp	(	const float4 &	Value,
		const float4 &	minv,
		const float4 &	maxv )

SIMD function "clamps" (clips) the specified packed values so that they are not lesser than "minv", and not greater than "maxv".

Parameters

Value	Value to clamp.
minv	Minimal allowed value.
maxv	Maximal allowed value.

Returns

The clamped value.

round()

float4 avir::round

(

const float4 &

v

)

SIMD rounding function, exact result.

Parameters

v	Value to round.

Returns

Rounded SIMD value.
