v?fmod

Compute the floating-point remainder of input vector 1/input vector 2.

Interface Definition

C interface:

void vsfmod(const int len, const float* src1, const float* src2, float* dst);

void vdfmod(const int len, const double* src1, const double* src2, double* dst);

Parameters

Parameter	Type	Description	Input/Output
len	Integer	Number of elements in the input vector. If len ≤ 0, an invalid parameter error is reported and the function returns.	Input
src1	Single-precision floating-point type for vsfmod Double-precision floating-point type for vdfmod	Input vector src1 with length len. If the pointer is null, a null pointer error is reported and the function returns.	Input
src2	Single-precision floating-point type for vsfmod Double-precision floating-point type for vdfmod	Input vector src2 with length len. If the pointer is null, a null pointer error is reported and the function returns.	Input
dst	Single-precision floating-point type for vsfmod Double-precision floating-point type for vdfmod	Output vector dst with length len. If the pointer is null, a null pointer error is reported and the function returns.	Output

Return Value

The floating-point remainder is returned for each group of operation values. The formula is: fmod(x, y) = x - trunc(x/y) * y
For special values, see the following table.

Examples

C interface:

    #define N 4
    const float src1[N] = {-8.0f, 25.0f, +INFINITY, -0.0f};
    const float src2[N] = {6.2f, -4.3f, -192.4, -3.1f};
    float dst[N] = {0};

    vsfmod(N, src1, src2, dst);
    printFArr("input1:", N, src1);
    printFArr("input2:", N, src2);
    printFArr("output:", N, dst);
 
    /**

     *  input2:  6.200   -4.300 -192.400   -3.100
     *  output: -1.800    3.500      nan   -0.000
