Hi,

I have a question:

I have a numerical variable, and I would like to compare it with a certain
number of fixed numbers and choose the one closest

for example:

the number variable that can have numerical values, the fixed numbers are:
3,6,9,12,15,
if the variable has value of 2, then I would like to change 2 to 3 because 3
is the closest number to 2.
if the variable has a value of 7, then I want to change 7 to 6 because 6 is
the closest number to 7.
if the variable has a value of 4.5, then either 3 or 6 can be the answer.

I think I can use if statement, but I am wondering if an array or another
easier method can do this?

Thanks for help!
