@Peter,
When you find time, can you please explain how the index in an array is calculated.
The index is an integer, but it is not calculated using the INT(x) function in case X is a FLOAT ?
Example:
random dice rolls can be calculated using 1+RND()*6
if I use these as index in a array (1,000,000 rolls) I get following distribution
Option default integer
Dim distribution(7)
For i=1 To 1e6
Inc distribution(1+Rnd*6),1
Next i
For i=0 To 7
Print i, distribution(i)
Next i
End
0 0
1 83119
2 166639
3 166889
4 166590
5 166382
6 166897
7 83484
Only when I explicitly use the INT(x) function I get a correct distribution.
Dim distribution(7)
For i=1 To 1e6
Inc distribution(Int(1+Rnd*6)),1
Next i
For i=0 To 7
Print i, distribution(i)
Next i
End

For i=0 To 7
Print i, distribution(i)
Next i
