Introduced in https://github.com/ruby/bigdecimal/commit/4792a917d806 `rb_absint_size` return the number of bytes needed to fit the absolute integer, but negative integers need the sign, so one more bit, and potentially one more byte. https://github.com/ruby/bigdecimal/commit/0f3d5d0eb7

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.
