The following table lists the available operators. For each operator, an example is given of the syntax of using a literal value as well as a cell reference. The type of value returned is given for each type of operator.

 Type of Operator Example Syntax Result Operator Description Literal & Literal Cell Ref & Literal Type Returned Binary Operators + Add 5 + 3 A1 + 3 double – Subtract 5 – 3 A1 – 3 double * Multiply 5 * 3 A1 * 3 double / Divide 5 / 3 A1 / 3 double ^ Exponent 5 ^ 3 A1 ^ 3 double & Concatenate "F" & "p" A1 & "p" string = Equal A1 <> 3 boolean < > Not Equal A1 = 3 boolean < Less Than A1 <3 boolean > Greater Than A1 > 3 boolean <= Less Than Or Equal A1 <= 3 boolean >= Greater Than Or Equal A1 >= 3 boolean Unary Operators - Negate -(5/3) -(A1/3) double + Plus +(5/3) +(A1/3) double % Percent (5/3)% (A1/3)% double

Operators specify the type of calculation that you want to perform on the elements of a formula. Most of the operators return double-precision floating point values for mathematical operations and boolean (or logical) values for comparison operators.

In Spread.Sheets, all arithmetic operators (including the unary +) check their arguments and return a #VALUE error if any of the arguments are strings that cannot be converted to a number. This is mathematically correct behavior and cannot be overridden. For example, the three formulas +B5 and 0+B5 and --B5 should all produce the same result and, in Spread.Sheets, they do.
