Reading a GA and displaying the value in decimal via PHP

[Bodo]

Hoi
Have a look at PDF:
http://www.knx.org/fileadmin/downloa....5.00%20AS.zip
Page 31 I think

3.10 Datapoint Types “2-Octet Float Value”
Format: 2 octets: F16
octet nr: 2 MSB 1 LSB
field names: FloatValue
encoding: MEEEEMMM MMMMMMMMM
Encoding:
FloatValue = (0,01*M)*2(E)
E = [0 … 15]
M = [-2 048 … 2 047], two’s complement notation
For all Datapoint Types 9.xxx, the encoded value 7FFFh shall always be used to denote invalid
data.
Range: [-671 088,64 … 670 760,96]
PDT: PDT_KNX_FLOAT

Hi,

I'm trying to read and display a GA (temperature) with PHP.
I've read the procedure on the KNX site, but I wonder if someone has already done it with PHP or similar ? (from ETS -> décimal)

Thank you.
