I try to convert the binary value
01000000 10001010 10111011 10001100to the value 4.33.
Also see the example:
Reproducable on this site:
http://binaryconvert.com/result_float.html?hexadecimal=408ABB8C
Is this doable in FME? And how?
Thanks!
I think a few lines of Python is justified here, e.g.
import struct
Â
flt = '01000000 10001010 10111011 10001100'
Â
f = int(flt.replace(' ', ''), 2)  # Remove spaces
print(struct.unpack('f', struct.pack('I', f))k0])Result:
4.335393905639648It should be fairly easy to incorporate into a PythonCaller.
If you don't mind python, struct is a standard library I think
import fme
import fmeobjects
import struct
Â
def processFeature(feature):
   Â
    binary = feature.getAttribute('value').replace(" ","")
    float = struct.unpack('f', struct.pack('I', int(binary,2)))Â0]
    feature.setAttribute("float",float)Â

Thanks for the quick reply!

Thanks for the working piece! Really appreciate it.

Thanks again for this @ebygomm​ it works great. Providing a working example is really fantastic for people like me. I always have a really hard time to get anything Python related working, but tweaking something existing, what works, is doable.Â
I believe combining FME and Python will return far better solutions then FME only.  I would love to do this more, but somehow learning it really gives me a struggle.
Note: I don't have a programming background. And I think a lot FME users are in the same boat, else they would have fixed most of their issues using Python.

My python knowledge is gained almost entirely from reading these boards. I've never used python outside of FME! I'd avoided pythoncallers completely until I had an issue that was worth the pay off in time spent v timesaved.

Fortunately there is an enormeous amount of Python tutorials out there, most of them free.

It's well worth the investment if you regularly work with non-trivial issues, in my opinion. Both within and without FME.
