Dear All,

I'm writing something to display a floating point variable. However, Str() function only display the integer part. Does anybody kown how to fix this?

e.g.

x.f = 2.2225
MessageRequester("Information", "x = " + Str(x), 0)

Thanks!

Hi!

Use this command to get desired result
string.s=StrF(variable.f, decimals.l)

Thanks Pupil,

It works now. However, please try the below code:

====== Begin ======

x.f = 1.0
y.f = 1.000001
For i = 1 To 100000000
x = x * y
Next i
MessageRequester("Information", "x = " + StrF(x,10), 0)

====== End ======

It show me x = 1.#INF

What does it mean?

Don't know but probably means that you number overflowed i.e. the largest number that can be presented by the IEEE 754 floating-point representation is in the neighborhood of 1.0*10^126 when you go above this you get infinity and that is probably what you got.. But it would be nice if it printed out INF instead of 1.#INF.

The following works:

Code: Select all

x.f = 1.0
y.f = 1.000001
For i = 1 To 10000000
x = x * y
Next i
MessageRequester("Information", "x = " + StrF(x,10), 0)

I only changed your "100000000" to "10000000",
so i looks like a overflow (like Pupil said).

Thanks.

Yes, I know it is the over-flow problem. However, there is no such problem in VB or VBA.
