Rounding to Multiple

Hello All,

I’m in the process of creating an image based scroller and need to adjust the width of the movie clip containing my images to integer multiples of 60. Say the width is 1230.4, I would like to round it to 1260.

I know I need to first round the decimal width to an integer, but calculating the closest multiple of 60 to the rounded number has me a stuck.

Any ideas?
