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.

When you change this to true, you may need to add more tests.

treat 0.0 and -0.0 of floating-point numbers specially for an optimization
and to correctly propagate its signbit to the result.
