RTCM 1005 message generation

[fjdbirot]

Hi all, thanks for the tremendous work done on this package. I was inspired by the sample script rtcmbuild.py to try to generate a RTCM 1005 message. The data parameter in my case then looks like this.

data = [
    ("DF002", 1005),
    ("DF003", 0),
    ("DF021", 0),
    ("DF022", 1),
    ("DF023", 1),
    ("DF024", 1),
    ("DF141", 0),
    ("DF025", 4381294.934),
    ("DF142", 1),
    ("DF001_1", 0),
    ("DF026", -109288.027),
    ("DF364", 0),
    ("DF027", 4618528.857),
]

Where DF025, DF026 and DF027 are the XYZ coordinates to be encoded. This raises an error

bits += f"{val:0{datasiz(dfd)}b}"
        ^^^^^^^^^^^^^^^^^^^^^^^^^
ValueError: Unknown format code 'b' for object of type 'float'

Do you have any thoughts on how to fix this ? Thanks a lot !

Apologies @fjdbirot. The rtcmbuild.py script was only intended as a crude academic illustration of how RTCM3 payloads are constructed from bits->octets->bytes. The code as it stands only works for unsigned integer values and is not viable as a means to generate real-world RTCM3 packets. I should have made this clearer in the comments and am minded to remove the example altogether, as it probably only serves to confuse. The pyrtcm library is purely a parser, not a generator. Sorry for the confusion.
