Hello, If you have experienced with Pascal language, we know that mod and div function, or you can see my example here: Code: n:= 5 mod 2; // 1 m:= 5 div 2; // will return to 2, 2x2 = 4 + 1 = 5. x:= 8 div 2; // will return to 4, 2x4 = 8 y:= 9 div 1; // will return to 9, 1x9 = 9 You can see reference here: http://wiki.freepascal.org/Div And now, There is alternative or a same function on PHP? Thanks.

According to Free Pascal Wiki: PHP provides the % operator, which is equivalent to mod. It will implicitly cast the operands to integers before execution. PHP also provides /, but it manages types like this: for the operation "$a % $b", If $a is int and $b is int and $a is divisible by $b ("divisible" is defined as "$b multiplied by an integer yields $a"), the quotient is returned as an int. If $a is int and $b is int and $a is not divisible by $b, the quotient is returned as a float. If $a or $b or both of them is float, the result is always a float, even if the float represents an integer (i.e. even if `$float == (int) $float` is true but `$float === (int) $float` is false) The integer division (div) in Pascal simply takes the floor value of the quotient, which is equivalent to a float cast to an int in PHP. Therefore, always putting (int) for the division expression, e.g. `(int) (7 / 2)` will work. Note that since the division operator in PHP, `/`, has lower precedence than the type casting operator `(int)`, you must parenthesize the division expression.
