there are 2 ways i found to get a whole number from a division in c++
question is which way is more efficient (more speedy)
first way:
Quotient = value1 / value2; // normal division haveing splitted number
floor(Quotient); // rounding the number down to the first integer
second way:
Rest = value1 % value2; // getting the Rest with modulus % operator
Quotient = (value1-Rest) / value2; // substracting the Rest so the division will match
also please demonstrate how to find out which method is faster
If you're dealing with integers, then the usual way is
Quotient = value1 / value2;
That's it. The result is already an integer. No need to use the floor(Quotient);
statement. It has no effect anyway. You would want to use Quotient = floor(Quotient);
if it was needed.
If you have floating point numbers, then the second method won't work at all, as %
is only defined for integers. But what does it mean to get a whole number from a division of real numbers? What integer do you get when you divide 8.5 by 3.2? Does it ever make sense to ask this question?
As a side note, the thing you call 'Rest' is normally called 'reminder'.remainder.
