- is the numerical subtraction operator. There are no surprises, except that subtracting from zero and using the unary - operator yields different results with one particular value: to demonstrate, the following is from interactive Run Mode.
OK A=-524287-4095/4096 OK PRINT -A 524288 OK PRINT 0-A Overflow (PRINT) OK
(The value of
-A cannot be added to zero, have zero added or subtracted from it, be multiplied by one, or be used in other expressions that should be no problem: more details are on the page 524287.999755859375 (Numerical Value).)
