Rounding to two decimal places

Post subject:  Rounding to two decimal places
Ok I started working on a game last week. Basicly it's going to be a turn based strategy game. One of the things I'm trying to do is give the player complete control of their army as in develop whatever weapons they can imagine weather it's a giant gravity bomb or a light weight assault rifle etc. Now what I want to know is if it's possible to round real numbers of when I display them using Draw.Text.

What I want to do is round off some numbers to two decimal places (eg. Money). Is it possible to do this using when using Draw.Text?

Thanks

multiply the number by 100, round, then divide by 100

example
4.265
426.5
427
4.27

yep, you could, and you don't even have to write your own rounding method, what i found in the F10 help was this
code:
put frealstr(1.125,0,2)

1.125 is a real, you can use your money variable or whatever variable to replace it, and 0 is the width, for formmating the adjustment, and 2 is the rounding precision

put 1.24214124214:0:2 rounds to 2 decimal places Smile also (since it already was bumped from last week)

But that won't work if he's using Draw.Text.

Here's the function I use:
Turing:
fcn roundn (value : real, nPlaces : int) : real
    var multiply : real := 10 ** nPlaces
    result round (value * multiply) / multiply
end roundn


For a normal round, you round to 0 decimal places. You can round negative or positive decimal places.
