Double trouble

[Edwin Knoppert]

I peek'd a double value in VB and PB.
They differ.

I need a PB variable (double) compatible with VB.

How?

These are the results of 123.456

VB:

119
190
159
26
47
221
94
64

PB:
0
0
0
32
47
221
94
64

The following example creates exactly the same problem!

#Compile Exe
 
Function PbMain
 
    Dim dbl As Double
    dbl = 123.456
 
    MsgBox Str$( Dbl ) & ", " & Format$( Dbl, "#.#################" )
 
End Function

Note: I can not make use of currency or extended precision.

The numeric literal 123.456 is a single precision value. Change it to:

dbl = 123.456#

To expand on that a little... most variable types are cross-compatible between PB and VB or, indeed, most other languages. A PowerBASIC SINGLE is the same as a Visual Basic SINGLE, a DOUBLE is a DOUBLE, a LONG is a LONG, and "rose is a rose is a rose"...

If you find otherwise, first suspect the method you're using for comparison or a similar coding problem.

Thanks, this works however, to provide a value this way is not that nice.

But fort. most values will be stored in a double value anyway.
(Not the way as in my test)
