There is a node called Percent used for floats, its actually the Modulo operator. Its often forgotten about when discussing order of operations so keep in mind it happens on the same level as Multiplication and Division 
I made New Vars default value 3.6833333 and the print returned 0.6833333! Another property of the modulo operator is checking for odd or even by comparing against 2 which might come in handy if youre using the Ying and Yang.
Edit: Which reminds me, you may want to start your array at 1 and go through to 60 rather than 0 to 59 just so it lines up with existing lookup charts.
