2297238 - WDA: Google Chrome CX_SY_CONVERSION_NO_NUMBER dump in CLUR_NW7_USER_AGENT_INFO

When using Google Chrome browser version 49 or higher, system raises exception CX_SY_CONVERSION_NO_NUMBER on ABAP Program CLUR_NW7_USER_AGENT_INFO.

The short text message is "'537.36 Google Favicon' cannot be interpreted as a number."

1. On the Source code part of the dump, on line 87 you can see the system is verifying if USER_AGENT_INFO-VERSION is a floating point number:

   |   86|* rule for "(Chrome, >= 8.0, *)"
   |>>>>>|  if user_agent_info-browser eq 'Chrome' and is_float( user_agent_info-version ) eq abap_true.
   |   88|    lightspeed_info-supported = abap_true. "#EC NOTEXT 
   

2. On the chosen variables section, you can see USER_AGENT_INFO-VERSION has some extra information and therefore cannot be interpreted as a number:
