Hi guys,
just wondering whether anyone can provide me with a simple example on
programming. I have

IF A > B THEN Left_Turn

but instead of A > B, i would like it to be maybe just 90% of B.
So the program i want is IF A > 90% of B THEN Left_Turn
just wondering how it is like in basicstamp language

thanks guys

Jeff

Try

IF A > (90*B)/100 THEN Left_Turn

This presumes that 90*B<=65535! You have to do the multiplication first
since it is integer math. For example, assume B=200.

B*90 = 18000
18000 / 100 = 180

However, if you compute B * (90/100) then you get B*0 or 0!

The Stamp evaluates left to right so the () are not strictly necessary, but
I put them there to make the point that the order is very important.

if (A > (90 * B / 100)) THEN Left_Turn

Or, if you need to implement proper rounding:

if (A > ((90 * B + 50)/ 100)) THEN Left_Turn

Archiver

Also, check into the Stamp's */ operator:

IF A > B */ 230 THEN Left_Turn

That is saying 230/256 instead of 90/100. But the two fractions are
very close. Another way is,

IF A > B ** 58982 THEN Left_Turn

which is saying 58982/65536, which is very close to 90/100.
