On the result of division and remainder of negative numbers

Before the fourth version of the algorithm read a question, now the compiler to try

Remainder and dividend same number

14÷-3 = -4 2

-14÷-3 = 4 -2

-14÷3 = -4 -2

On the quotient, the expression A/b Chamber of Commerce to 0 rounding, that is, negative number up rounding, positive number downward rounding, similar to positive negative number rounding.

If you do not know what upward downward rounding, simple notation is a number of axes, from left to right in turn, you put the axis counterclockwise rotation 90 °, from the bottom to the top in turn, the upward downward rounding is not a lot of simple memory. For example, 4.3 down to 4, rounded up to 5,-3.22 down to 4, rounded up to 3, the axis vertical look on the line, I am so memory.
