v?sind
Interface Definition
C interface:
void vssind(const int len, const float* src, float* dst);
void vdsind(const int len, const double* src, double* dst);
Parameters

Type |
Description |
Input/Output |
|---|---|---|---|
len |
Integer |
Number of elements in the input vector. If len ≤ 0, the system displays a message indicating that the value of len is invalid. |
Input |
src |
|
Input vector src with length len. If the pointer is null, the system prompts a null pointer error. |
Input |
dst |
|
Output vector dst with length len. If the pointer is null, the system prompts a null pointer error. |
Output |
Return Value
- The sine y of degree x is returned for each operation value, that is, y = sind(x) = sin(x * π/180). y ∈ [-1, +1]
- For special values, see the following table.

Example
C interface:
float src[LEN] = {0.0f, 2.0f, INFINITY, NAN};
float* dst = (float*)malloc(sizeof(float) * LEN);
if (dst == NULL) {
printf("Malloc Failed!\n");
return;
}
vssind(LEN, src, dst);
