From: 0x0dea+redmine@... Date: 2015-07-07T16:22:46+00:00 Subject: [ruby-core:69888] [Ruby trunk - Bug #10594] Numeric#clamp Issue #10594 has been updated by D.E. Akers. In the case of `min > max`, the options seem to be these: * return `nil` * return the receiver * raise an `ArgumentError` Given that the first two are likely to cause something else to explode down the line, it seems best to just stop at the source of the error. ---------------------------------------- Bug #10594: Numeric#clamp https://bugs.ruby-lang.org/issues/10594#change-53305 * 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.
