[REBOL] Re: retrieving values in binary files

Hi Hugues,
> I can easily retrieve integer values stored in big-endian or little-endian
format, but an don't know how to retrieve floating values stored as floats or
doubles in binary format (big-endian or little-endian).
I do not know if this can help, but given a 4/8 byte binary read from a file
which represent a float/double IEEEE number, you could do:
float: make struct! [num [float]] none
change third float #{0000C841}
float/num ; == 25
double: make struct! [num [double]] none
change third double #{0000000000003940}
print double/num ;==25
For big/little endian you should reverse binary before using it.
