2021-01-13[ruby/bigdecimal] Allow digits=0 in BigDecimal(flt) and Float#to_dKenta Murata
Using dtoa of mode=0, we can determine the number of digits in decimal that is necessary to represent the given Float number without errors. This change permits digits=0 in BigDecimal(flt) and Float#to_d, and these methods use dtoa of mode=0 when the given digits is 0. Internal implicit conversion from Float also uses digits=0.

2020-12-15Import bigdecimal 2.0.2 (#3905)Kenta Murata
* remove duplicated include * Make BigDecimal#round with argument < 1 return Integer Fixes [Bug #12780] * Use a higher default precision for BigDecimal#power and #** When a fractional power is given, increase the precision if the precision isn't specified via power's second argument: Float: increase by 15 (rough number of decimal precision in float) BigDecimal: increase by adding similar precision modifier as done to calculate the base precision. Rational: double the precision, since a BigDecimal is created, but the created BigDecimal uses the same precision. Increasing the precision for these power calculations has the obvious tradeoff of making the calculations slower. Fixes Ruby Bug #17264 * Use DBLE_FIG for a Float value * Version 2.0.1 Co-authored-by: pavel <pavel.rosicky@easy.cz> Co-authored-by: Jeremy Evans <code@jeremyevans.net> Notes: Merged-By: mrkn <mrkn@ruby-lang.org>
