While doing a sum on a floating-point range I have realized simple SUM(4) cannot be directly used
It requires translation of FP range into the integer range, which is basically a hack.

Doing a sum over the FP range in a loop is terribly slow - any ideas why?

Use Optimization --> Numeric on the function.
(R/Click on the function, select Optimization ---> Numeric.

That worked. Thanks!

I don't see that here. "for loop" is always the winner. deeper @ kernel level.

AS NTDMA has suggested, Numeric Optimization did the trick. Its was purely to do with my incompetence.
