Description

tanh(x) computes the hyperbolic tangent of x.

Standard

FORTRAN 77 and later, for a complex argument Fortran 2008 or later

Class

Elemental function

Syntax

x = tanh(x)

Arguments

x - The type shall be real or complex.

Return value

The return value has same type and kind as x. If x is complex, the imaginary part of the result is in radians. If x is real, the return value lies in the range ~~(削除) - 1 \\leq tanh(x) \\leq 1 (削除ここまで)~~(追記) $- 1 \leq tanh(x) \leq 1$ (追記ここまで).

Example

program test_tanh
 real(8) :: x = 2.1_8
 x = tanh(x)
end program test_tanh
