Notes:
- Units - CPE (Clocks per Element)
- Performance was measured on "working" interval (double precision: [ 0.0001, 10000.0 ] for both arguments; single precision: [ 0.0001, 10000.0 ] for both arguments)
- Data - vectors of 1000 elements with random generated numbers.
- All data was collected with 64-bit libraries.
