Function 'tan'

     

This function returns the result of a trigonometric tangent function.

 

Syntax:

  {INT_VAR|FLO_VAR}= tan({NUM_EXPR})
 

I/O parameters:

{NUM_EXPR} Value to be calculated.
-  
 

Return value:

 
{INT_VAR|FLO_VAR} Integer or float value containing the result of this function.
 

Example:

  Declaration of Variables
 
 10 ask(DOCU_FLOAT_1,"Please enter a value!")	
 20 DOCU_FLOAT_2 = tan(DOCU_FLOAT_1)	
 30 put(DOCU_FLOAT_2)	
  Result: (For DOCU_FLOAT_1 = 45)
 
In order to prevent errors, the float/double type must be used if results can be expected to be either very large or very small (<2^-31 or > 2^31).
