How should I name a method that does this...?

Question

I have a method that receives two range endpoints - start of range and end of range and an integer.

It checks to see if the integer falls between the two end points and returns either the integer or the corresponding end point if the integer falls outside the boundary.

Example 1:

• RangeStart = 0; RangeEnd = 10; Value = 5; Returns 5

Example 2:

• RangeStart = 0; RangeEnd = 10; Value = -4; Returns 0

Example 3:

• RangeStart = 0; RangeEnd = 10; Value = 23; Returns 10

Question: What should I call a method that does that? I had called it IntWithinRange, but I don't think I like that.

Any ideas?

Answer 1

How about ConstrictToRange / LimitToRange / ConfineToRange? Something of this form would be seem to convey the meaning quite succinctly.

Answer 2

I've seen it called Clamp().

And that's what M$ calls it.
