Standard arithmetic operators

 

All arithmetic operators take one argument E in parenthesis, where E is any valid equation.

•   abs  returns the absolute value of the argument. For example, .  
•   arctan  is the hyperbolic tangent function, returning the value whose tangent is the given argument. For example, .  
•   cos  returns the cosine of its argument. For example,  
•   exp  returns E to the power of its argument. For example,  
•   ln  returns the natural logarithm of the argument E. A non-positive argument causes an error. For example,  
•   sgn  returns one of three values according to the sign of its argument: zero if the argument is zero; if the argument is negative; and if the argument is positive. For example .  
•   sin  returns the sine of its argument. For example, .  
•   sqr  returns the square of its argument. For example, .  
•   sqrt  returns the square-root of its argument. An error will be reported if the argument is negative. For example, .  
•   trunc  returns the integer truncation of its argument. For example, .
