Function

# vvtanf

Calculates the tangent of each element in an array of single-precision values.

## Parameters

parameter 1

The output array, y.

parameter 2

The input array, x.

parameter 3

The number of elements in the arrays.

## Discussion

If x is +/-0, the result preserves the signed zero.

If x is +/-inf, the result is NaN.
