The goal of FP would be to make it straightforward to modularize both large and small details. The notion that you can modularize a low level algorithm does not preclude modularizing a high level business process. This is a good thing because I've found in my own experience that it's hard to say at what level you're at when implementing something. Implementing a standard deviation function? Is it happening over in memory data or persistant? Is it going to happen in parallel when it can? Is it going to be distributed across servers? Suddenly you're back at the high level.
