v?fmod

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, the system displays a message indicating that the value of len is invalid.

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, the system prompts a null pointer error.

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, the system prompts a null pointer error.

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, the system prompts a null pointer error.

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.

    Input Value 1 (src1)

    Input Value 2 (src2)

    Output Value (dst)

Example

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
