Tangent of a Multiple of Pi

Source: R/api.R, R/api-generics.R
nv_tanpi.Rd

Element-wise tan(pi * x). You can also use tanpi(). Like base R's base::tanpi(), it is exact for a whole argument and NaN at the half integers, where the tangent has its poles.

Usage

nv_tanpi(x)

Arguments

x

(arrayish)
One input. Can be any numeric data type: a float keeps its own, and an integer one is converted to the default float data type (see default_dtypes()). An R value materializes at its default data type and is converted in the same way.

Value

(arrayish)
Has the input's shape, and its data type – or the default float data type (see default_dtypes()) where the input was an integer one.
