[edk2-devel] [PATCH] RedfishPkg/RedfishCrtLib: handle floating point number in JSON

["Nickle Wang via groups.io" <nicklew=nvidia.com@groups.io>]

When the value type is defined as number in Redfish schema, floating
point number is allowed. RedfishCrtLib raises assert without handling
this case now. Follow the way in EDK2 to call AsciiStrDecimalToUintnS
and handle the floating point number.
