Splittable

Goal

This gem solves the problem of several decimal places in divisions where the result must be presented in cents, that is converting the division result to only two decimal places and the difference is attributed to the first plot.

Installation

Add this line to your application's Gemfile:

gem 'splittable'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install splittable

Usage

Using division method:

Splittable.division(value: 0.1188888, quantity: 3)

Result: the total truncated value was divided by the number of plots informed and attributed the difference in the first installment:

=> [0.5e-1, 0.3e-1, 0.3e-1] # => [0.05, 0.03, 0.03]

Default precision is 2 decimal places, but, you can customize this with precision parameter:

Splittable.division(value: 10, quantity: 3, precision: 3)

Result:

=> [0.3334e1, 0.3333e1, 0.3333e1] # => [0.334, 0.333, 0.333]

Using normalize method:

Splittable.normalize(value: 100.003, installments: [33.33, 21.433, 43.33333])

Result: all values are truncated and them the difference is attributed in the first installment:

=> [0.3524e2, 0.2143e2, 0.4333e2] # => [35.24, 21.43, 43.33]

In this method, you have the same optional precision parameter:

Splittable.normalize(value: 100, installments: [33.33333333, 33.33333333, 33.33333333], precision: 3)

Result:

=> [0.33334e2, 0.33333e2, 0.33333e2] # => [33.334, 33.333, 33.333]
