tanh

Details #

tanh(x) takes exactly one argument and returns its hyperbolic tangent, a number between -1 and 1. The argument is a plain number, not an angle.

Parameters #

Takes 1 argument. {{ tanh(text) }}

Examples #

tanh(0)

round(tanh(1), 4)

Gotchas #

• Calling it with no argument or two arguments is an error: tanh() takes 1 argument, got 2.

• Anything that isn't a number is an error: tanh() needs a number, got text. Numeric text such as "0.5" is accepted.
