Notes:
  1. Units - CPE (Clocks per Element)
  2. Performance was measured on "working" interval (same for both single and double precision: [ 0.000001, 100000.0] for arguments
    a
    ,
    b
    ,
    scalea
    , and
    scaleb
    ; [ 0.000001, 100000.0 ] for arguments
    shifta
    , and
    shiftb
    )
  3. Data - vectors of 1000 elements with random generated numbers.
  4. All data was collected with 64-bit libraries.
