Restricting variables to 2 decimal places

-----------------------------------

i know that if you want to restrict the number of decimal spaces on an output it would be :

variable : 0 : 2

However, I am font drawing variables in my program, and these variables have values assigned to them

For example balanceowing := opening + interest
Font.Draw realstr (balanceowing,5,), 120 , 230, font1, white)

How would you restrict this output to 2 decimals? Sinse it does have a values assigned to it via other variables and it is font drawn


Also if anyone knows how to get rid of the 7.14321e6 exponent junk would you be able to give me the solution? Thanks

I havent tested this this might work
var v2 := realstr(variable, 2)
v2 := v2(1..index(v2,".")+2)

I am fairly sure you simply mean to round a value to 2 decimal places instead of just cutting it off?

var pi : real := 3.14159
put pi
put round(pi * 100) / 100

var pi : real := 3.14159 
put frealstr (pi, 2, 2)
