Float precision is only for the display of strings, not internal
calculations, and not for editable fields.
In other words, if you have a float variable r, it might equal 3.14159
r=3.14159
put r
-- 3.1416
(note - default precision is 4, so it rounds when displaying)
set the floatPrecision =2
put r
-- 3.14
set the floatPrecision =5
put r
-- 3.14159
However, if you're trying to control an edit fields, that's different. As
far as director is concerned, it's just a string. It doesn't pay attention
to whether or not you're entering decimals or letters, or IP addresses or
Morse code... it doesn't care. If you want to limit the field, you'll have
to secretly absorb the keypresses, then display only the ones you want. In
other words, make it a non-editable field, suck up the keypresses, build
the string on the fly, and display it.
Alternatively you could probably use the keyDownScript to intercept the
keypresses and decide if you want to pass them on, but I haven't tried that
for years and don't remember if it'll cut it or not...
