How to determine if a number is whole or decimal

[Hobbyist_PHPer]

Hi, can someone tell me how to determine if a number is a whole or a decimal value number?

As I told you in your other thread, for your purposes it makes more sense to automatically convert to a decimal value of 1.0 or 1.5.

 

If you insist on checking what type it is, there are functions like is_float(), etc.

Where is this number coming from?

Right, but don't I still have to then parse it as a string, to get the whole number and the decimal value? Then I'd have to determine if it is .5 or .0, if it is .5 then it would output 30 or if it was 0, it would be 00

a loop,

for ($i=1;$i<24.5;$i+=0.5)

You really should have that loop go from 0 to 23.5, 12:30 am is 0.5

Right, thanks

 

is this what you were talking about with the number format?

$i = number_format($i, 2, '.', ' ');

[Jessica]

I *think* you can leave the 4th param out since you will never have a number in the thousands, but you want your digits set to 1 based on your other code.

 

But yes that is what I meant.

<?php
for ($i=0.0;$i<23.5;$i+=0.5){
echo number_format($i, 1).'<br>';
}

Edit: for other thread, sorry.
