Rounding up to .47 and .97

I am trying to write a piece of code that will round a number up to the nearest .47 or .97 using the following code:

var regPrice = Math.ceil(minPriceMult * 2)/2 - 0.03

This code works for the most part. However for values of .48, .49, .98 and .99 it incorrectly rounds them down to the nearest .47 or .97 respectively rather than up. I am aware of why this happens; the .03 is subtracted after the rounding, however i have been unable to find a working alternative to the code above.

Any help on solving this problem would be appreciated.

:point_right: You need to add first, then subtract after:

var regPrice = Math.ceil((minPriceMult + 0.03) * 2)/2 - 0.03
