2021-02-04[ruby/bigdecimal] Fix uint64 conversionKenta Murata
Stop using logarithm to compute the number of components. Instead, use the theoretical maximum number of components for buffer, and count up the actual number of components during conversion. https://github.com/ruby/bigdecimal/commit/9067b353ac

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.
