QBASIC programmers - need help!

[jderou]

I have a program written in basic that generates gcode based on user input. my problem is sometimes the output looks like this:
G0 X 4.525002 Y-1.400002
Their is no reason that .000002 should be added to these numbers, it just randomly appears.
All of my variables are dimensioned as single
can anyone help?

You need to round them off or truncate them to a certain number of decimals. I haven't used Qbasic, so can't tell you how to do it.

If you want to post the qbasic program here, I'll take a look and let you know where to round it at.

Dimension as single is probably causing the slight rounding error.

When you output the line use a statement like:
PRINT USING "#####.###"; X;

Here is the file

how would I format output when the print statement looks like this:

PRINT #1, "G0 X"; X(m) - XA - 1.875; " Y"; RT(j, m) - YA - .75

Its a pretty long program, the first few pages are just menu commands though.

[wjbzone]

try this:

format$="\ \ #####.### \ \ #####.###"
PRINT #1, USING format$ "G0 X"; X(m) - XA - 1.875; " Y"; RT(j, m) - YA - .75

I use

Print #1, format$(num,"##.0000")


nevermind... the above is for Visual Basic

You could use 'INT'
eg.
X = INT(X*1000+.5)/1000
Y= INT(Y*1000+.5)/1000
This will round to three decimal places.
