Table 10.A shows the effects of leading zero suppression (LZS) and
trailing zero suppression (TZS). It presumes that your system installer has
set a format of X5.2 (integer 5 digits, decimal 2 digits) in AMP. Different
formats would result in different decimal point placement compared to
those shown below, but the end result would be comparable.

Using LZS and TZS with G-Codes
The following table illustrates how the control interprets different G-Codes
in leading zero and trailing zero suppression modes.
Leading Zero Suppression Mode
(decimal assumed at end if not programmed)
Trailing Zero Suppression Mode
(2-digit G-code assumed unless decimal point programmed)
