Javascript to force decimals in 0.25 steps
I have a few input values on a form that must be in 0.25 steps, how do I force this ? alternatively how do I automatically enter the correct vales as the user types and disallow any other values ie: as the firstnumber is typed (say 3) then .00 is added, then as the decimal point and the first decimal value is entered which must be either 0, 2, 5 or 7 then the appropriate second decimal is added which would be 0 or 5 as appropriate. I guess I will need an alert for any other values that might be entered in error?
I have googled and there are plenty of solutions to round to the nearest decimal but not to actually force 0.25 steps
I am sorry, I have absolutely no idea where to start
