Function Hypot

The Hypot function computes a square root of sum of two squared elements.

Performance:

Notes:
1) Units - CPE (Clocks per Element)
2) Performance was measured on "working" interval (double precision: [ -10000.0 ; 10000.0 ] for both arguments; single precision: [ -10000.0 ; 10000.0 ] for both arguments)
3) Data - vectors of 1000 elements with random generated numbers.
