Used to find the difference between two numbers or to indicate the negative value of a numeric expression.
result = number1 - number2
The - operator syntax has these parts:
Part Description result Any numeric variable. number Any numeric expression. number1 Any numeric expression. number2 Any numeric expression.
In Syntax 1, the - operator is the arithmetic subtraction operator used to find the difference between two numbers. In Syntax 2, the - operator is used as the unary negation operator to indicate the negative value of an expression.
For information on when a run-time error is generated by Syntax 1, please see the Arithmetic Operators table.
For Syntax 2, as for all unary operators, expressions are evaluated as follows:
In Syntax 2, if the resulting number is nonzero, result will be equal to the resulting number with its sign reversed. If the resulting number is zero, result is zero.
- If applied to undefined or null expressions, a run-time error is raised.
- Objects are converted to strings.
- Strings are converted to numbers if possible. If not, a run-time error is raised.
- Booleans are treated as numbers (0 if false, 1 if true).
- The operator is applied to the resulting number.
