javascript - toFixed method without rounding to five digit

Question

I have a number var x = 2.305185185185195;

x = x.toFixed(5);

x = 2.30519 but I require this without rounding i.e. 2.30518

I read some thread with two decimal places but could not find for five decimal places.

Any help would be appreciated.

Answer 1

You can use an apropriate factor and floor it and return the result of the division.

Basically this solution moves the point to the left with a factor of 10^d and gets an integer of that and divided the value with the former factor to get the right digits.

function getFlooredFixed(v, d) {
    return (Math.floor(v * Math.pow(10, d)) / Math.pow(10, d)).toFixed(d);
}

var x = 2.305185185185195;

document.write(getFlooredFixed(x, 5));
