Notes:
1) Units - CPE (Clocks per Element)
2) Performance was measured on "working" interval (double precision: [ -10000, 10000.0 ] × [ -10000, 10000 ] for both arguments; single precision: [ -10000.0, 10000.0 ] × [ -10000, 10000 ] for both arguments)
3) Data - vectors of 1000 elements with random generated numbers.
