Function Documentation

◆  StepEx()

Float64 StepEx	(	Float64	a ,
		Float64	x
	)

返回 1.0 if x is greater than or equal to a , else 0.0 .

参数

[in]	a	A double-precision floating point value.
[in]	x	A double-precision floating point value.

返回

The step value ( 0.0 or 1.0 ).

◆  Boxstep() [1/2]

Float32 Boxstep	(	Float32	a ,
		Float32	b ,
		Float32	x
	)

返回 0.0 if x is less than a and 1.0 if x 大于 b , else returns x mapped on the range [ a , b ].

参数

[in]	a	A single-precision floating point value.
[in]	b	A single-precision floating point value.
[in]	x	A single-precision floating point value.

返回

The box stepped value between 0.0 and 1.0 .

◆  Boxstep() [2/2]

Float64 Boxstep	(	Float64	a ,
		Float64	b ,
		Float64	x
	)

返回 0.0 if x is less than a and 1.0 if x 大于 b , else returns x mapped on the range [ a , b ].

参数

[in]	a	A double-precision floating point value.
[in]	b	A double-precision floating point value.
[in]	x	A double-precision floating point value.

返回

The box stepped value between 0.0 and 1.0 .

◆  Smoothstep() [1/2]

Float32 Smoothstep	(	Float32	a ,

		Float32	x
	)

返回 0.0 if x is less than a and 1.0 if x 大于 b , else returns x mapped on the range [ a , b ].

注意

The mapping is smoothed using an ease-in/ease-out curve.

参数

[in]	a	A single-precision floating point value.
[in]	b	A single-precision floating point value.
[in]	x	A single-precision floating point value.

返回

The smoothed stepped value between 0.0 and 1.0 .

Float64 Smoothstep	(	Float64	a ,
		Float64	b ,
		Float64	x
	)

返回 0.0 if x is less than a and 1.0 if x 大于 b , else returns x mapped on the range [ a , b ].

注意

The mapping is smoothed using an ease-in/ease-out curve.

参数

[in]	a	A double-precision floating point value.
[in]	b	A double-precision floating point value.
