You can do it that way - but looking at the C-code it looks like you can also
just do this:
local myval = tag.value
or this:
local myval = tag()
In both of those cases 'myval' will be a Lua number of the tag value as well,
because a FieldInfo object for a "m3ua.parameter_length" field value is a
FT_UINT16 type internally, so getting its value should get you a Lua number.
Any FieldInfo of an internal type FT_FLOAT/DOUBLE/UINTx/INTx will give a Lua
number when its value is retrieved. (except FT_UINT64/FT_INT64) Or at least
the code looks like it will do that, I haven't tried it myself.
