numeral().format() accepts a 2nd parameter which is the rounding function to use.

In your case, you probably want Math.floor - numeral(4986444.0).format('0.00a', Math.floor)

You can also use bitwise negation like this numeral(4986444.0).format('0.00a', n => ~~n)

I hope this helps

numeral.fn._format = numeral.fn.format;
numeral.fn.format = function (a, b) { return numeral.fn._format.call(this, a, b || numeral._.defaultRoundingFunction); };

numeral._.defaultRoundingFunction = Math.round;
numeral.setDefaultRoundingFunction = (fn) => { numeral._.defaultRoundingFunction = fn || numeral._.defaultRoundingFunction; }
