Converts a Rational to a BigDecimal.
The required precision parameter is used to determine the amount of significant digits for the result. See BigDecimal#div for more information, as it is used along with the #denominator and the precision for parameters.
r = (22/7.0).to_r # => (7077085128725065/2251799813685248) r.to_d(3) # => #<BigDecimal:1a44d08,'0.314E1',18(36)>
