Hello,
I'm trying to convert an int into a float in php. For
example: I get
this value: 1065353216 which represents 1.00 in float.
I tried:
* $floatValue = (float)$intValue;
* settype($intValue,"float");
* settype(&$intValue,"float");
but nothing works. They all return the initial $intValue.
When I do a
gettype($floatValue), they all return me double.
The reason I want to do that is to port some C++ code into
php. Does
anyone know a solution?

Quite honestly PHP isn't a programming language so the need
to convert
the numbers as such has never arised. The only way I can
think of is to
do some heavy string parsing which will cost you some
processor time.
I'll try and come up with a function.

I'm just curious, how the heck 1065353216, an integer, get's
converted
to 1.00 ???
The only thing I can think of is that you insert a
"." after the first
1 and THEN you have a float.
Cuz 1065353216 can be a float value as well, what makes a
float
DEFINITLY is the decimal portion, and 1065353216 has no
decimal
portion what-so-ever, does it ?
So something like this could do your trick:
$float=$number.'.'.substr($number,1);
This would transform "1065353216" into
"1.065353216" and NOW you have
a decimal portion. With some number formating functions you
can the
get your "1.00" format.

Dan was a little mistaken, the number isn't an int, but a decimal
number. It gets converted to 1.00 in float as per the IEEE single
precision (i'm hoping he's using single precision) specification.
