cf.Data.tanh¶

Data.
tanh
(inplace=False)[source]¶ Take the hyperbolic tangent of the data elementwise.
Units are accounted for in the calculation. If the units are not equivalent to radians (such as Kelvin) then they are treated as if they were radians. For example, the the hyperbolic tangent of 90 degrees_east is 0.91715234, as is the hyperbolic tangent of 1.57079632 radians.
The output units are changed to ‘1’ (nondimensional).
New in version 3.1.0.

Examples:
>>> d.Units <Units: degrees_north> >>> print(d.array) [[90 0 90 ]] >>> e = d.tanh() >>> e.Units <Units: 1> >>> print(e.array) [[0.9171523356672744 0.0 0.9171523356672744 ]]
>>> d.Units <Units: m s1> >>> print(d.array) [[1 2 3 ]] >>> d.tanh(inplace=True) >>> d.Units <Units: 1> >>> print(d.array) [[0.7615941559557649 0.9640275800758169 0.9950547536867305 ]]
