modulo helper about ember-truth-helpers HOT 5 CLOSED

Adding mod helper is a good idea, but I am wondering if we should put mod helper into ember-truth-helpers. To me, ember-truth-helpers should only return boolean instead of numbers.
If we can a addon called 'ember-math-helpers' then that would be great. After that we can use something like this : {{if (eq (mod 10 2) 0)}}

@jeffrey008 Yes, this would broaden scope slightly. What about the simple case of (mod i) representing i % 2 === 0 returning just true or false? Or maybe call them (even i) and (odd i)? Still, I can see if you don't want in this module.

Good idea. Here is my implementation of the helper is-even

export function isEvenHelper(params) {
  if (type of params[0] !== number){
    Ember.assert(`Expected number: get ${typeof params[0]} instead`);
 } 
  return params[0] % 2 === 0;
}

Anyway this is just the first draft of the function, so feel free to modify it.
Also I am wondering if we need a is-odd helper, although we can use the result of is-even to know it is odd or not, there may be a case where the params is not integer.

please note that a mod helper is already a part of https://github.com/shipshapecode/ember-math-helpers so there is probably no need to recreate it here too

Makes sense!
