Calculates the arctangent of each element in an array of single-precision values.
Declaration
func vvatanf(_: UnsafeMutablePointer<Float>, _: UnsafePointer<Float>, _: UnsafePointer<Int32>)Discussion
Parameters:
- parameter 1
The output array, y.
- parameter 2
The input array, x.
- parameter 3
The number of elements in the arrays.
The calculated values are in the range [-pi/2, pi/2].
If x is +/-0, the result preserves the signed zero.
If x is +/-inf, the result is +/-pi/2.
