Tan
Gets the tangent of the specified expression.
Format
Tan(<expression>)
Parameter
Return value
Returns the double precision real tangent value.
Description
Gets the tangent of the expression specified in the <expression> parameter.
In the <expression> parameter, specify the value in radians. To convert an angle value to a radian value,
multiply by π/180.
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
If a value is assigned to the return value variable or the variable is not used in an expression, a "Syntax error"
error will occur.
If the format is written incorrectly, such as writing the macro function name incorrectly, omitting a comma, or
omitting a half-width space, a "Syntax error" error will occur.
Usage Cautions
• None.
Example
Gets the tangent of 45°.
The result is shown below.
