If you need precision with floats or doubles you can use BCMath
Arbitrary Precision Mathematics Functions.

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!
