Question

Suppose I have a method like:

def calculate(alpha, beta)
  # do stuff
end

How do I make sure that when I call calculate(1.0,2.0) it will always treat the arguments as decimals and not as floats or integers?

Answer 1

If you’re looking for params to be handled as a BigDecimal, you can use the following:

    require 'bigdecimal'
    require 'bigdecimal/util'

    def calculate(alpha, beta)
      alpha_bigdec = alpha.to_d
      beta_bigdec = beta.to_d
    end
