Question on division (Java) - Also Perl, PHP, Python ...
Q:
What's the difference between % and /?
A:
/ returns the result of a division
% returns the remainder when you do a division.
Divide 18 by 7 you get 2, with a remainder of 4 (i.e. 4 left over).
so 18/7 give 2, and 18%7 gives 4.
And from Tcl/Tk and Expect... you can see the float v integer considerations of a division!
% expr 18 / 7
2
% expr 18. / 7
2.57142857143
% expr 18 % 7
4
