errors in programs
A few programs would attempt to divide by zero if the 2nd argument is 0 (zero).
In that special case, the absolute value of the first argument should be returned.
A number of examples don't show the results if either argument is negative.
REXX Version 1
These results seem to be wrong:
- the GCD of 14 and 0 and 7 is 14 should be 7
- the GCD of 0 and 7 is 0 should be 7
- the GCD of 0 and 0 is 0 should be ???
correct:
- the GCD of 7 and 0 is 7
