Find out if value is Equally divided..

[ljnet]

Hi there, hoping someone has answer to a problem i have..

I want to work out if a particular value is equally divided by a certain number.

For example:

$number1 = 9;
$number2 = 3;

is $number1 equally divided by $number2 ? In this case yes, so return a positive result.

I guess you would have to divide number1 by number 2, but how do you work out if the result is a whole number or a decimal?

Any ideas?

Use the modulus operator (%)

To expand on Shrikes comment:

The modulus operator(%) gives you the remainder of a division operation.

I.E.
10 / 4 = 2.5 : in human division
10 / 4 = 2 : in integer division (php does integer division)
10 % 4 = 5 : the remainder of 10 / 4

10 / 5 = 2 : in human division
10 / 5 = 2 : in integer division
10 % 5 = 0 : divided evenly no remainder

eoghain, just wanted to clarify your explanation of the modulus operator (%). Actually, the results of your explanation, so as to not create any confusion for ljnet.

10%4 actually equals 2 and not 5. 4 divides into 10 twice with a remainder of 2. It looks like you are taking the .5 as a remainder of 5, or maybe you just had a mistype. Either way, in your first example, the remainder (and thus, the result of the modulus operation) is 2.

Thanks Defender, might have been a typo but more than likely was a math mistake.

I suck at math and spelling so ofcourse I became a programmer. ;->
