IE browser not supporting Math.trunc()

Question

The below code is working fine in Chrome, but in IE browser I am seeing the below console error:

object does not support property or method 'trunc'

Code:

var Days = (new Date(date1) - new Date(date2)) / 50;
if (Math.trunc(Days) > 45)) {
 alert("it should be less than 45 days");
}

Answer 1

Math.trunc is not supported in IE as MDN states, please read here.

Instead you could use polifylls:

if (!Math.trunc) {
    Math.trunc = function (v) {
        return v < 0 ? Math.ceil(v) : Math.floor(v);
    };
}

Hope that clarifies.
