Sin

Function Sin

The Sin function computes a sine.

Performance:

	Default processor	Pentium® III processor	Pentium® 4 processor	Itanium® processor
vsSin (HA version)	38.9	40.5	19.0	6.2
vdSin (HA version)	50.2	50.1	36.7	7.3

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
4) "Default" means X87 code for all IA-32 processors
5) Performance of "default" version was measured on Pentium® III processor

Notes:
1) *        X87 code for all processors
2) **      Pentium® III processor
3) ***    Pentium® 4 processor
4) **** Itanium® processor
5) Logarithmic scale is used for "Vectors Size" axis

Maximal observed error for the whole function domain:

	Default processor	Pentium® III processor	Pentium® 4 processor	Itanium® processor
vsSin (HA version)	0.80	0.80	0.80	0.50
vdSin (HA version)	0.92	0.92	0.51	0.51

Notes:
1) Units - ULP (Units in The Last Place)

Special values:

Function	Input Argument	Result	Default processor	Pentium® III processor	Pentium® 4 processor	Itanium® processor
vsSin/vdSin (HA version)	0	0	+	+	+	+
	NaN (Both QNaN and SNaN)	NaN (Raise Invalid Exeption for SNaN)	+	+	+	+
	+/- Inf	NaN	+	+	+	+
