[ruby-core:69771] [Ruby trunk - Bug #10594] Numeric#clamp

Issue #10594 has been updated by Motohiro KOSAKI.


>+    double num_dbl = NUM2DBL(num);
>+    double beg_dbl = NUM2DBL(begp);
>+    double end_dbl = NUM2DBL(endp);

If num is Bignum, the above code could make data loss. I think.
Why can't we use "num"'s <, <= or <=> operator?

----------------------------------------
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.
