get Math.round to round up to next minute even if over by a second

Related to my previous question javascript math.round and math.floor work fine in IE and Opera but not Chrome, Safari or Firefox. Getting NaN

I have updated fiddle here http://jsfiddle.net/8VmPm/

The reason behind this script may seem a little cloudy so I'll try to explain. CDRs (Call detail records) from a certain network operator come in seconds for voice records and bytes for data records. I'm writing a "calculator" to convert seconds to minutes and bytes to megabytes.

I also took it a step further and added some example plans in there to check for overage.

My problem (which is simply cosmetic, but I am OCD like that) is in the first calculation (Math.round(minusage / 60)) (lines 22 and 23 in fiddle). I need it to round up to the next minute even if the value entered in the Usage Used field is over by 1 second.

Example:

  1. In the Minute Which Plan? dropdown, pick Plan A (500 Minutes)
  2. In the Usage Used field, enter in 30001 (which is 500 minutes and 1 second)
  3. Click the Calculate button

Results in the Usage Summary field will be:

500 minutes used. -1 of 500 minutes remaining

Currently, it will not say, "501 minutes used" until the value entered in Usage Used field is 30030 or greater (for Plan A)

I need it to go to the next minute up even if over by 1 second (otherwise it'll confuse the non-techies who will be using it)

Any help with this matter would be greatly appreciated!

Take a look at Math.ceil(...). It is a JavaScript method for rounding up to the nearest integer. Here is a link to the MDN page.
