Integer Division.

[RichardF]

I have a small question, can anyone explain :

int(29.5/15) = 1

(29.5\15) = 2

thank in advance ...

int(29.5/15) - Normal divison, then truncated
The bracketed part is normal division. The number is then truncated, not rounded to an integer value.

(29.5\5) - Integer division
The order of events for this is:
1. Inputs rounded to integers
2. Division carried out
3. Result truncated to integer

(truncated means everything after the decimal point is cut-off rather than rounded-up)

Hope this helped

Technically int(x) returns the "highest integer which does not algebraically exceed x". So:

For positive numbers int(29.5) = 29

For negative numbers int(-29.5) = -30

Unfortunatley, VB has a variety of ways of calculating integer results from floating point operations. I say 'unfortunate' because, as you have discovered, they can give different results. And there are differences between the implicit conversions and the explicit conversions. The following minor example illustrates some of this further:

Private Sub Command1_Click()

' Explicit conversions
Print Int(29.5 / 15)
Print Int(29.4 / 15)
Print
Print CInt(29.5 / 15)
Print CInt(29.4 / 15)
Print
' Implicit conversions
Print (29.5 \ 15)
Print (29.4 \ 15)
End Sub
