Notes:
- Units - CPE (Clocks per Element)
Performance was measured on "working" interval (double precision: [ -10000.0, 10000.0 ] for HA and LA, [ 1000.0, 10000.0 ] for EP for both arguments; single precision: [ -10000.0, 10000.0 ] for HA and LA, [ 1000.0, 10000.0 ] for EP for both arguments)
Data - vectors of 1000 elements with random generated numbers.
All data was collected with 64-bit libraries.
