the problem i have is that when i make a box or cube in darkbasic and i put for example 10 as the size, when i display the size it says its actually 9.9999994 or something like that. is there a way to round off the number so it would be 10.0? bascally i need a command that rounds off numbers to the point you want. do i have to make a function to do this?

and in a totally unrelated question, how do i get the value that ENTRY$()returns to be stored to a variable?

thanks alot,
doug

Usually you would just add 0.5. However, in DBPro, its a bit more involved - find the decimal point and ignore everything after that (or you can use my VALF command - but that only works with strings).

a$=entry$()

I came up with this after coming across a similar problem of wanting to show the time to 1 dp. You can use this, although it doesn't actually round the numbers up - it just knocks off the unwanted digits. You could adapt it to round up quite easily though if you needed to be that accurate.

or if you want a plain integer for the size, you could just put the size from OBJECT SIZE X() into an integer instead of a float.

i'm not sure why DBP has problems with float accuracy. they say it's because it's difficult to represent numbers with the floating point format PCs use but i never have these weird inconsistencies with C++.

OK enough of that damn DBP fanboy banner. i'm NOT a DBP fanboy in any way. i haven't used DBP in over a year, and i don't really plan on using it again.
