[Ted Huntington]

Is there some easy way to fwrite a 32 bit int or float?

ok I see to use the "pack" command, but now how do I format to 32 bit
little endian?

I should have type "signed 32 bit little endian" and little endian float.

I basically solved this problem of writing a 32 bit float in little endian on
a big endian computer using:
$num2=pack("f",$num);
fwrite($fp,$num2[3],1);
fwrite($fp,$num2[2],1);
fwrite($fp,$num2[1],1);
fwrite($fp,$num2[0],1);

for floating point (I am working on a UNIX [big endian] making a file for i86
[little endian]).

The more info, the better, perhaps some body else will search and find this
if ever the need.

There was a large discussion on this about two weeks ago, check the
archives on 'big endian'
