[SOLVED] string to double

[alin19]

i must compare a lot of numbers  like this:

 

4734.1400 and 4734.14

the problem is that the first one is in string format and the second one into double and they are not equal, how can i change the type?

Since you did not respond with the solution you found, here is the solution for anyone else with the same problem:

 

You would use the (double) cast IE:

 

<?php
$firstDouble = (double)"4734.1400";
$secondDouble = 4734.14;

if ($firstDouble == $secondDouble) {
     echo 'Yep';
}else {
     echo 'Nope';
}
?>

 

I am not sure if the .1400 will cause it to not be correct, but if so, you can use number_format to just make it 2 decimal places.

As long as you use the equality operator(==) and not the identical operator(===) you don't need to worry about types. Two variables are considered equal (but not identical) regardless of their type.
