working with array with floats

[Gunnar G]

I have read a file with the file() command and it contains numbers, numbers
that are larger than 2^32 and now I wonder, will this be a problem if I do
arithemtcis, or is there some easy way to force it to use consider the
array as floatingpoint numbers?

I didn't know sci.bio.paleontology was that low traffic until I tried read
the thread "Where is everyone?" and found it to be expired.

I leave that to the people who actually learned the basics, is suspect it
might.

You can use floatval() on a string without problems. However, depending on
how the data in that file is stored, you might want to look into the
fscanf() function.

No worries! PHP will automatically convert types for you to hold the
number you want.

Although PHP's dynamic typing should handle this properly, it might be
useful to convert the string to an unsigned int with sprintf, if you run
into issues:

/* maybe pretend we're looping */
$uintArray[] = sprintf('%u', trim($currentLine)); // this way, huge ints
won't become negative

This is useful when you are converting IPs to longs.
