Subject: [ruby-core:69917] [Ruby trunk - Bug #10594] Numeric#clamp

Issue #10594 has been updated by Ferdinand Niedermann.


> That `min > max` should raise an `ArgumentError` seems the only logical conclusion.

I agree. I'll send another pull request including that.

Bug #10594: Numeric#clamp
https://bugs.ruby-lang.org/issues/10594#change-53342

* Author: Chris Johnson
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: 2.1.2
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
This is basically a re-opening of the feature request of issue#4573 (https://bugs.ruby-lang.org/issues/4574), which was closed due a naming debate.

It seems the standard naming for restricting a number to a specified range is indeed 'clamp'.  (1)(2)(3)

As such, can we use Yusuke Endoh's original patch with the naming adjustments?  If so, I can provide accordingly.

Cheers.
