toStringWithDecimalPlaces throws RangeError on zero

[Bazinga9000]

Reproduction Steps:
ExpantaNum.ZERO.toStringWithDecimalPlaces(3,true)
raises the following error:

Uncaught RangeError: toFixed() digits argument must be between 0 and 100
    at Number.toFixed (<anonymous>)
    at decimalPlaces (eval at <anonymous> (test.js:102:12), <anonymous>:1213:31)
    at P.toStringWithDecimalPlaces (eval at <anonymous> (test.js:102:12), <anonymous>:1250:28)
    at <anonymous>:1:17

This works in the console on https://naruyoko.github.io/ExpantaNum.js/test.html, and also still errors when replacing 3 with any other integer.

Can reproduce the error when running new ExpantaNum(x).toStringWithDecimalPlaces(y,true), where x is any value that, after division by 10^y, results in a number less than or equal to 10^-100.

In particular, new ExpantaNum(1e-97).toStringWithDecimalPlaces(3,true) raises the same error, and so does new ExpantaNum(1e-96).toStringWithDecimalPlaces(4,true).

Likely a bug in the following function:

ExpantaNum.js/ExpantaNum.js

Lines 1207 to 1212 in df78659

	var decimalPlaces=function decimalPlaces(value,places){
	var len=places+1;
	var numDigits=Math.ceil(Math.log10(Math.abs(value)));
	var rounded=Math.round(value*Math.pow(10,len-numDigits))*Math.pow(10,numDigits-len);
	return parseFloat(rounded.toFixed(Math.max(len-numDigits,0)));
	};
