Description

The function computes sine of vector elements.

Note that arguments abs(a[i]) ≤ 213 and abs(a[i]) ≤ 216 for single and double precisions respectively are called fast computational path. These are trigonometric function arguments for which VM provides the best possible performance. Avoid arguments that do not belong to the fast computational path in the VM High Accuracy (HA) and Low Accuracy (LA) functions. Alternatively, you can use VM Enhanced Performance (EP) functions that are fast on the entire function domain. However, these functions provide less accuracy.

Special Values for Real Function v?Sin(x)
Argument Result VM Error Status Exception
+0 +0    
-0 -0    
+ QNAN VML_STATUS_ERRDOM INVALID
- QNAN VML_STATUS_ERRDOM INVALID
QNAN QNAN    
SNAN QNAN   INVALID

Specifications for special values of the complex functions are defined according to the following formula

Sin(z) = -i*Sinh(i*z).
