tanh value float x
Use tanh to calculate, in radians, the hyperbolic tangent of a floating point number. This trigonometric function works the same way as its equivalent in the C math library.
Out-of-range values return "not a number" (NaN).
Example:
include "omtrig.xin"
process
output "The hyperbolic tangent of pi/3 is "
|| "d" % (tanh (pi / 3))
|| " %n"
; Output: "The hyperbolic tangent of pi/3 is 0.780714435359268"
