Making a variable do math from other variables
|
Title kinda says it all, could really use help here.
I'm trying to make Var1 = the divided sum of Var2 and Var 3.
The following code isn't working.
| Code: |
#VAR Var1 %eval( @Var2/@Var3)
#VAR Var1 (%eval( @Var2/@Var3))
#MATH Var1 (@Var2/@Var3) |
Also, this will result in a decimal type number less than 1 (which may be my problem). Therefor I'd like to show 0.00 (in truth i'm just looking for a percentage)
Any help, please? |

Math is generally done as integer math. The use of floating point values is often less precise then properly handled integer methods. You should multiply first then divide. Finally %insert the decimal point in the correct place just when displaying.
