What does the
% in a calculation? I can’t seem to work out what it does.
Does it work out a percent of the calculation for example:
4 % 2 is apparently equal to 0. How?
The % (modulo) operator yields the remainder from the division of the first argument by the second. The numeric arguments are first converted to a common type. A zero right argument raises the ZeroDivisionError exception. The arguments may be floating point numbers, e.g., 3.14%0.7 equals 0.34 (since 3.14 equals 4*0.7 + 0.34.) The modulo operator always yields a result with the same sign as its second operand (or zero); the absolute value of the result is strictly smaller than the absolute value of the second operand .
6%2 evaluates to
0 because there’s no remainder if 6 is divided by 2 ( 3 times ).
7%2 evaluates to
1 because there’s a remainder of
1 when 7 is divided by 2 ( 3 times ).
So to summarise that, it returns the remainder of a division operation, or
0 if there is no remainder. So
6%2 means find the remainder of 6 divided by 2.
