Rounding Numbers

[Sup3rkirby]

I don't think there is a current method to do this, but what I need to do is, round an integer(not decimal) to the nearest 5(or basically a number other than 1).

For instance I have a 37 from an equation, and i want to round it to 35, because it is the nearest 5. If it were a 38, it would round to 40.

And thoughts on how to do this? Thanks in advance.

just do some simple maths

<input type="text" onChange="alert(Math.round(this.value / 5) * 5);">

Math.round --> round to nearest whole number
Math.floor --> round down to whole number

Math.round --> round to nearest whole number
Math.floor --> round down to whole number

sorry i missed your point.

You cannot mention Math.floor without Math.ceil

<script type="text/javascript">
alert(Math.ceil(2.00000001));//3
alert(Math.floor(3.99999999));//3
alert(Math.round(2.5));//3
</script>
