I am confused by the comment about the definition on lines 13+ of the example - which is not accurate when invoking mod when 'num' is positive and 'div' negative. Applying the definition to
we haveSo unless I misunderstood, the definition should be changed to something like:
"The mod function is defined as the amount by which a number exceeds the largest integer multiple of the divisor that is not greater than that number, except when the number is positive and the divisor negative, in which case the result is the amount by which the number exceeds the smallest multiple that is not smaller than the number."
Or, change the implementation to something similar to:
to fit the current definition.
