How to input mathematical equations?

[Leonardo_Czuy]

Is there a way to input mathematical equations directly into AutoCAD? For example, if I want to input 9*3 = 27, so I don't have to calculate it manually.

You can use a Field with a Formula.

Hi,

you can to this by using CAL or simplier, by using LISP.

Read about CAL in your help and about LISP too [F1]

Lisp,

Note1 the prefix-notation! (* 9 3) (+ 1 2 3 4) (/ 27 9)

Note2 if your devide statement uses integers only, the result will also return just the integer part! (/ 1 3)=0,  (/ 1.0 3)=0.333, (/ 1 3.0)=0.333, (/ 1.0 3.0)= 0.333

CAL is so powerful. Rarely run into anyone who even knows about it.
