How do I locate the largest integer in an array?

[gannon_w]

Sorry if this has been asked before and it seems simple.

I have an array of data with both positive and negative numbers. I want to locate the largest number (farthest from zero) regardless of sign. But I will need to retain the sign because I will be dividing every number in the array by that number to normalize the array to values between 1 and -1?

Thanks in advance!
