Module: VectorNumber::NumericRefinements::BigDecimalToD

Defined in:
lib/vector_number/numeric_refinements.rb

Overview

Note:

‘BigDecimal` needs to be defined for this refinement to activate.

Refinement module to change Kernel#BigDecimal so it works with #to_d.

Examples:

without refinements

BigDecimal(VectorNumber[2]) # can't convert VectorNumber into BigDecimal (TypeError)

with refinements

require "vector_number/numeric_refinements"
using VectorNumber::NumericRefinements
BigDecimal(VectorNumber[2]) #=> 0.2e1

Since:

  • 0.2.1
