Re: problem with string & floats in PHP

<?php$var = '5.812E-08';var_dump($var);$var =
(float)$var;var_dump($var);var_dump($var + 2);?>Outputs:string(9)
"5.812E-08"
float(5.812E-8)
float(2.00000005812)
All you need is to cast it (float) to float, (int) to int.

Hello, Im designing a website in which I have to read some data (numbers)
from a txt file and then send this data to a function which prints a
graphic with them. When I read the data I save it in an array and the
numbers are in this format: 5.812E-08. I have read the php documentation
about it, and I have use the example given there to check which type is
the data saved in the array. The response I got is
$vectorIc[1]== 5.812E-08 type is string

I dont understand why. In the documentation it is clear that this kind of
data should be considerer float, or thats what I understood. I cant
continue with my web designing if I dont get to turn the vector elements
into float numbers, because the function that prints the graphic gives
errors when recieving strings. I would be very thankful if you could help
me trying to solve this. In using PHP 4.4.7 and Apache 2.0.59.

Thank you very much!
