Simple LUA for those who know LUA

[Momos 103]

Like the title says, it should be a simple LUA question, but the answer eludes novices like me  

 

I have in a scene a generated value which is a number with decimals.  I need a function to round up that number to the next multiple of 15.

 

For example if the generated number is 3.56 then it should round it up to 15; if the number is 17.87 it should round it up to 30 etc

 

Can this be done or am i dreaming ?

 

Thank you

Hope this helps.
