cf.Count.tan¶

Count.
tan
(*args, **kwargs)[source]¶ Take the trigonometric tangent of the data elementwise.
Units are accounted for in the calculation, so that the tangent of 180 degrees_east is 0.0, as is the tangent of 3.141592653589793 radians. If the units are not equivalent to radians (such as Kelvin) then they are treated as if they were radians.
The Units are changed to ‘1’ (nondimensional).
The “standard_name” and “long_name” properties are removed from the result.

Examples
>>> f.Units <Units: degrees_north> >>> print(f.array) [[45 0 45 ]] >>> g = f.tan() >>> g.Units <Units: 1> >>> print(g.array) [[1.0 0.0 1.0 ]]
>>> f.Units <Units: m s1> >>> print(f.array) [[1 2 3 ]] >>> f.tan(inplace=True) >>> f.Units <Units: 1> >>> print(f.array) [[1.55740772465 2.18503986326 0.142546543074 ]]
