◆ clamp() [1/2]

template<class T >

constexpr const T clamp	(	const T &	v,
		const T &	lo,
		const T &	hi
	)

constexpr

Clamp function. Returns lo if v < lo and hi if v > hi. Otherwise returns v.

Parameters

[in]	v	Value to be clamped.
[in]	lo	Lower clamping value.
[in]	hi	Higher clamping value.
