Syntax:int intdiv ($dividend, $divisor)
Parameters: the function takes two parameters as follows:
- $divnd: this signed integer parameter refers to the number to be separated.
- $divisor: this signed integer parameter refers to to the number to be used as the divisor.
Return type : This function returns the calculated ratio.Examples:
Input: $dividend = 5, $divisor = 2 Output: 2 Input: $dividend = -11, $divisor = 2 Output: -5
Exception / Error::The function raises an exception in the following cases:
- If we pass the divisor 0, the function will throw a DivisionByZeroError.
- If we pass PHP_INT_MIN as the dividend and -1 as divisor, an ArithmeticError is thrown.
The following program illustrates how intdiv works in PHP:
// PHP -code to illustrate the work
// intdiv() functions $dividend = 19; $divisor = 3; echo intdiv ( $dividend , $divisor );
?> Output:
6
Looking so far, many might think this function is equivalent to
floor ($dividend / $divisor)
but an example will clarify the difference.
// PHP code to differentiate
// intdiv() and floor() $dividend = -19; $divisor = 3; echo intdiv ( $dividend , $divisor ). "" . floor ( $dividend / $divisor ) ;
?> Output:-6 - 7
Important points to pay attention to : - The intdiv() function returns the quotient of an integer division.
- The function can throw exceptions, so the developer should tackle the edge cases.
- The function is not equivalent to the floor function applied to float division or "/".
