Let's say I have a numeric field and a button to increase the value and
a button to decrease the value. When I click the increase button, I want
it to increase to the next highest value that is evenly divisible by 20.
So if the field has a value of 19, a click will set the value to 20. If
the field has a value of 121, a click would increase it to 140.
I know I could do it by adding (or subtracting in the case of a
decrease) but is there a more elegant and/or faster way to do that?
Geoff Canyon just published this in another thread:
--------------------
function roundUp x,i -- rounds x up to the next i
return ((x - .00001) div i + 1) * i
end roundUp
put roundUp(curValue,20) into field "blah"
--------------------
Seems elegant and very readable to me.
