NumPy Support¶. The magnitude of a Pint quantity can be of any numerical scalar type, and you are free to choose it according to your needs. For numerical applications requiring arrays, it is quite convenient to use NumPy ndarray (or ndarray-like types supporting NEP-18), and therefore these are the array types supported by Pint.

The arctangent of x is defined as the inverse tangent function of x when x is real (x ∈ℝ). When the tangent of y is equal to x: tan y = x. Then the arctangent of x is equal to the inverse tangent function of x, which is equal to y: arctan x= tan-1 x = y. Example. arctan 1 = tan-1 1 = π/4 rad = 45° Graph of arctan.
