to_d

        # Complex.to_d

(from ruby core)
---
    cmp.to_d             -> bigdecimal
    cmp.to_d(precision)  -> bigdecimal

---

Returns the value as a BigDecimal.

The `precision` parameter is required for a rational complex number.
This parameter is used to determine the number of significant digits for
the result.

    require 'bigdecimal'
    require 'bigdecimal/util'

    Complex(0.1234567, 0).to_d(4)   # => 0.1235e0
    Complex(Rational(22, 7), 0).to_d(3)   # => 0.314e1
