Feature #12245
optional parameter ndigits to Integer#floor, Integer#ceil, Float#floor, Float#ceil
Description
Related to [Feature #12244].
I think that Integer#floor, Integer#ceil, Float#floor, and Float#ceil should have optional parameter ndigits, as well as round methods.

Updated by I think that would make sense.
I usually add an extra method call afterwards to round it manually (or, if not .round then to use it as a string and sprintf, % or .ljust / .rjust output it).
I should also note that newcomers often ask on IRC how to round / display something properly, so anything that may be of help here, is good I think. (It will be typical question such as how to display a float like 3.0 as 3.000, if only for properly padded output with other float values that will have 3 slots past the . like 2.983 and so on)
