Function Round
The Round function computes a rounded to nearest integer value for each vector element.

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