Float objects represent inexact real numbers using the native architecture’s double-precision floating point representation.

BigDecimal utility library.

To use these functions, require ‘bigdecimal/util’

The following methods are provided to convert other types to BigDecimals:

String#to_d -> BigDecimal
Float#to_d -> BigDecimal
Rational#to_d -> BigDecimal

The following method is provided to convert BigDecimals to other types:

BigDecimal#to_r -> Rational
