|Property/method value type:||Number primitive|
|Argument list:||anOperand1||A numeric value to be subtracted from|
|anOperand2||A numeric value to be subtracted|
Subtraction is indicated when two operands are separated by a minus sign.
The value on the right is subtracted from the value on the left. The result is the difference between the two values.
Subtraction behaves identically to addition, as if the formula:
a - b
a + (-b)
The associativity is left to right.
Refer to the operator precedence topic for details of execution order.
