tand

Compute the tangent of x expressed in degrees.

Base.Math.tand — Function
tand(x::T) where T -> float(T)

Compute tangent of x, where x is in degrees. If x is a matrix, x needs to be a square matrix.

Throw a DomainError if isinf(x), return a T(NaN) if isnan(x).

Julia 1.7

Matrix arguments require Julia 1.7 or later.
