SECH _ _ _ _ _ _ _ _ _ _ _ _ operator

The sech operator returns the hyperbolic secant of its argument.

syntax:

<expression> is any valid scalar REDUCE expression, <simple\_expression> is a single identifier or begins with a prefix operator name.

examples:

sech abc; 

  SECH(ABC) 



sech(0); 

  1 



sech 4; 

  SECH(4) 



on rounded; 


sech(4); 

  0.0366189934737 



sech log 5; 

  0.384615384615

sechreturns a numeric value only if rounded is on. Then the expression is calculated to the current degree of floating point precision.
