Formula Operators and Functions
Formula operators and functions are used in entering the formula items that are used to build the formula.The following operators and functions are available. 
Operators
	- Plus +, Arithmetic expression
 
- Minus -, Arithmetic expression
 
	- Multiplication *, Arithmetic expression
 
- Division /, Arithmetic expression
 
	- Comma , , Separator in a Function
 
- Open Parenthesis (, Arithmetic and Function
 
- Close Parenthesis ), Arithmetic and Function 
 
Functions
	- ABS (n): Absolute value of n 
 
- CEIL (n): Smallest integer greater if equal to n 
 
	- COS (n): Cosine of n in radians 
 
- COSH (n): Hyperbolic cosine of n 
 
- DECODE (expr, search1,return1, [search2,return2,]…[default]): If expr equals any search, return the following return; if not returns default 
 
- EXP (n): e raised to the n:th power 
 
	- FLOOR (n): Largest integer equal to or less than n 
 
- LN (n): Natural logarithm of n, where n > 0 
 
- LOG (m,n): Logarithm, base m, of n 
 
	- MOD (m,n): Remainder of m divided by n 
 
	- NVL (expr1,expr2): expr2, if expr1 is null, otherwise expr1 
 
	- POWER (m,n): m raised to the n:th power 
 
	- ROUND (n[,m]): n rounded to m decimals; m defaulted to 0 SIGN (n): If n <0, -1; If n =0, 0;If n >0, 1 
 
- SIN (n): Sine of n in radians 
 
	- SINH (n): Hyperbolic sine of n 
 
	- SQRT (n): Square root of n; if n < 0,NULL 
 
	- TAN (n): Tangent of n in radians 
 
	- TANH (n): Hyperbolic tangent of 
 
	- TRUNC (n[,m]): n truncated to m decimals; m defaults to 0
