Update. I have run some tests and I'm happy it's not the sin() and cos()
functions that are the issue. At least part of the problem is to do with
variable types and or variable declarations. The following vb test code gives
different results between Wine and Windows:
Private Sub Command1_Click()
Label1.Caption = testfunction(2100, 1845, 3960, 2460)
End Sub
Public Function testfunction(x1, y1, x2, y2)
'slope calculation
tmp1 = y1 - y2
tmp2 = x1 - x2
tmp3 = tmp1 / tmp2
testfunction = tmp3
End Function
On windows it returns the result 0.330645161290323, whereas under Wine it
returns 0.
The workaround is to declare the variable types passed to the testfunction eg.
Public Function testfunction(x1 as double, y1 as double, x2 as double, y2 as
double)
'slope calculation
...
The following declaration also returns 0 under Wine:
Public Function testfunction(x1, y1, x2, y2) As Double
'slope calculation
...
