Seems as if "0.0" and "0", is just plain strings of bricks... and the result is
zip..!
First there have to be a value for the beginning to use.. The total value,
timelengt, size...
Find your way so you get the path of having numbers..not strings.
Brake it up, and track it through 'message' in menu at right, (CTLR+M)in
Director. Set the Lingo-code of 'put eq' (the variables you are tracking down).
And do so with the rest of the variables you mess with.
'Floatprecision' gives the decimals, you only make the maths in your target
code. Concentrate on that first..and use parenthesis in frequent to box in your
separate math-rituals..
For measuring % for sounds, it's hard to get the actual length in seconds or in
bytes - in a unit scaled for an external file. One have to put it's value into
by the file-name procedure as I recall it. Even some problems with internal
sound files and might be so for other files too..
If you are aiming for % in a game or edutainment whatever ...it is probably
easier to have the full knowledge of the total length or sum or what might be
considered.
