Purpose
Tangent function.
Class
Elemental function
Argument type and attributes
- X
- An INTENT(IN) REAL
or type
complex.
Result type and attributes
Same as X.
Result value
The result value approximates tan(X).
- If X is of type real, it is considered a value in radians.
- If
X is of type complex, its real part is considered a value in radians.
Examples
TAN(1.0) has the value 1.5574077, approximately.
TAN((1.000000,
0.000000)) has the value (1.557408, 0.000000), approximately.
| Specific Name | Argument Type | Result Type | Pass As Arg? |
|---|---|---|---|
| TAN | default real | default real | yes |
| DTAN | double precision real | double precision real | yes |
| QTAN | REAL(16) | REAL(16) | yes 1 |
