float Qore::tan ( )

This function variant does nothing at all; it is only included for backwards-compatibility with qore prior to version 0.8.0 for functions that would ignore type errors in arguments.

Code Flags:: RUNTIME_NOOP

number Qore::tanh ( number n )

Returns the hyperbolic tangent of the given value.

Code Flags:: CONSTANT

Parameters

n	the value to process

Returns: the hyperbolic tangent of the given value

Example:: my number $x = tanh($y);
