Floor

Function Floor

The Floor function computes a rounded towards minus infinity integer value for each vector element.

Performance:

		Dual-Core Intel(R) Xeon(R) processor 5100 Series	45nm Intel(R) Core(TM)2 Duo processor	Intel(R) Itanium(R) 2 processor
single	HA	2.33	1.07	2.12
	LA	2.33	1.07	2.12
	EP	2.33	1.07	2.12
double	HA	4.21	1.94	2.12
	LA	4.21	1.94	2.12
	EP	4.21	1.94	2.12

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