There's also e- if the number is <1e-6

Can we do something like:

if(vRounded.indexOf('e') !== -1) {
    vRounded = vRounded.replace(/[.]?0+e/, 'e');
} else if(vRounded.indexOf('.') !== -1) { // why did we have lastIndexOf here? indexOf should be the same, right?

Good call. Revised in 5891651.

vRounded = vRounded.replace(/[.]?0+$/, '');
}
return Lib.numSeparate(vRounded, separators);
