Hi there,
I do have a text value inside a variable: exif[FNumber] = 56/10 which I
would like to save as a float value: 5,6 into a database.
How can I compute this 56/10? I tried things like calculate() or math()
but did not find the propper function to do this.
Can anybody help, please?
if you know the string is always in the form: "number / number"
you might do something like:
<?php
$str = "56/10";
$bits = explode("/", $str);
$num1 = floatval($bits[0]) / floatval($bits[1]);
echo $num1;
?>
another way to go *might* be to use eval() - note that eval() is
almost *always* the wrong solution to a problem:
<?php
$str = "56/10";
eval("\$num1 = {$str};");
echo $num1;
?>
Thank you in advance,
Merlin
Hi,
thank you that works. But unfortunatelly the notation out of this
calculation is with a comma instead of a point. is there a way to have
the output with a . instead of a ,
Example: 5.6 instead of 5,6
thank you for your help,
Merlin
