Paisa

Having trouble figuring out where to put the commas in Indian money? Are you being lazy and defaulting to hundreds of thousands and millions instead of lakhs and crores? Default no more! Paisa is here to save you.

Installation

Add this line to your application's Gemfile:

gem 'paisa'

And then execute:

$ bundle

Or install it yourself as:

$ gem install paisa

Usage

// Format paise - if you have your money in Rupees, multiply by 100 to get the number of paise.
assert_equal '3.34', Paisa.format(334)
assert_equal '9,393.34', Paisa.format(939_334)
assert_equal '792,83,83,393.34', Paisa.format(792_838_339_334)

// Use formatWithSymbol to get Paisa to add the official Rupee symbol for you
assert_equal '₹', Paisa::SYMBOL
assert_equal '₹3.34', Paisa.format_with_sym(334)
assert_equal '₹9,393.34', Paisa.format_with_sym(939_334)
assert_equal '₹92,83,83,393.34', Paisa.format_with_sym(92_838_339_334)
assert_equal '₹192,83,83,393.34', Paisa.format_with_sym(192_838_339_334)

// Pass an optional second parameter to force decimal precision to be set. 
Paisa.format(12345678987, precision: 0) // "12,34,56,789" 
Paisa.format(10000, precision: 2) // "100.00"
Paisa.format_with_sym(10000, precision: 2) // "₹100.00"
