String with decimal points

[wimal]

(setq a 12.2)
(setq b 7.
(setq c (+ a b))
(alert  (rtos c))

 

This display 20

How to change this to display as 20.0

[Grrr]

My 2 cents:

_1$ (setq a 12.2)
12.2
_1$ (setq b 7.
7.8
_1$ (setq c (+ a b))
20.0
_1$ (rtos c)
"20.0000"
_1$ (getvar 'lunits)
2
_1$ (getvar 'luprec)
4
_1$ (setvar 'luprec 1)
1
_1$ (rtos c)
"20.0"
_1$ 

or just:

_1$ (rtos c)
"20.0000"
_1$ (rtos c (getvar 'lunits) 1)
"20.0"
_1$

Look at rtos function help (rtos c 2 1)

 

(Rtos number mode precision)
1 scientific
2 Decimal
3 Feet decimal inches
4 Feet fraction inches
5 Fractional

Be aware of the effect of DIMZIN on the result; my Consistent rtos function is a possible solution to counter this effect.

Thanks Mr Lee Mac. Your explanation is very useful. Please can you explain me what function create the _$ and _1$
