Subtraction (-)

Details

The Subtraction operator produces the difference between two numerically interpreted operands. It interprets any leading, valid numeric characters as the numeric values of the operand and produces a value that is the remainder after subtraction.

Examples

The following example performs subtraction on two numeric literals:

 WRITE 2936.22 - 301.45 // 2634.77

The following example performs subtraction on two locally defined variables:

 SET x = 4
 SET y = 5
 WRITE "x - y = ",x - y // -1

The following example performs string arithmetic on two operands that have leading digits, subtracting the resulting numerics:

 WRITE "8 apples" - "4 oranges" // 4

If the operand has no leading numeric characters, ObjectScript assumes its value to be zero. For example:

 WRITE "8 apples" - "four oranges" // 8
