DIMTZIN System Variable

Type: Integer
Saved in: Drawing
Initial value: 0

Controls the suppression of zeros in tolerance values.
DIMTZIN stores this value when you enter it on the command line
or set it under Primary Units in the Annotation dialog box.
DIMTZIN values 0–3 affect feet-and-inch dimensions only.

0 Suppresses zero feet and precisely zero inches

1 Includes zero feet and precisely zero inches

2 Includes zero feet and suppresses zero inches

3 Includes zero inches and suppresses zero feet

4 Suppresses leading zeros in decimal dimensions (for example, 0.5000 becomes .5000)

8 Suppresses trailing zeros in decimal dimensions (for example, 12.5000 becomes 12.5)

12 Suppresses both leading and trailing zeros (for example, 0.5000 becomes .5)

我一直以为rtos的输出结果只跟函数后面指定的模式和精度有关，没想到不是这样。是我太想当然了。受教了

(rtos number [mode [precision]])

The rtos function returns a string that is the representation of number according to the settings of mode, precision, and the system variables UNITMODE, DIMZIN, LUNITS, and LUPREC.
