Cannot write floating point values with _write()

[skygreenslade]

I cannot write floating point values with _write(). Instead "null" is being written, and no error or return value is provided.

Example which creates the issue:

async with BAC0.start(ip=_ip) as bacnet:
        result = await bacnet._write(f'{_device_ip}:{_port} analogOutput 1 presentValue 0.1 - 3')
        print(f'\nResult: {result}\n')

Output (truncated):

Result: None

I think this may be due to the regex parsing the write arguments parsing a word for the value. Is there any workaround for this?
