Android Question Maths Problem in B4X

[Theera]

Refer to this ,I'm looking for Maths' Formulas for B4X
Assume In VB : 12 \6 =2
What's that in B4X?

 

[Sagenut]

Not sure but it could be

Log(12 Mod 6)

Post other calculations example if this is not the answer.

It is an integer division. Like 17\4 = 4
17 mod 4 = 1

 

[Sagenut]

It is an integer division. Like 17\4 = 4
17 mod 4 = 1

So in that case 12 \ 6 = 2.
Right?

 

[Johan Schoeman]

So in that case 12 \ 6 = 2.
Right?

Yes

 

[Johan Schoeman]

So in that case 12 \ 6 = 2.
Right?

13\6 = 2 as well

 

[Sagenut]

In this case I think that there is an error in the opening question.

I might be wrong but from memory that is what VB does when using \

 

[Sagenut]

What about

Log((11 / 4).As(Int))

or

Dim numb as Int = (11 / 4)

 

[Daestrum]

I think this gives the effect you want
(a - (a mod b)) / b

Yes, in VB there is the possibility to write the division using the slash or backslash character. Using the backslash, the whole result would be returned, discarding the remainder.

In B4X:

Dim Result As Int
Result = 13 / 2
Log(Result) '6

In B4X:

Dim Result As Int
Result = 13 / 2
Log(Result) '6

Even so:
Log((13/2).As(Int)) ' 6

It's called floor division. Here is the tested code:

    Dim x As Int
    Dim y As Int = 2
    Dim result As Int

    For x=1 To 20
    result = Floor(x / y) ' Perform division and discard the fractional part
    Log($"${x}->${result}"$) ' Outputs: Result
    Next

Results:
1->0
2->1
3->1
4->2
5->2
6->3
7->3
8->4
9->4
10->5
11->5
12->6
13->6
14->7
15->7
16->8
17->8
18->9
19->9
20->10

 

[LucaMs]

result = Floor(x / y) ' Perform division and discard the fractional part

Superfluous; try the same loop so:
result = x / y

Floor would be required if you declared Result as Float or Double.

 

[emexes]

Floor would be required if you declared Result as Float or Double.

Or depending on what you need to happen below zero.

 

[LucaMs]

Or depending on what you need

I need.. urgently a few million euros (only )

 

[emexes]

I need.. urgently a few million euros (only )

I have negative euros, but you are welcome to as many of them as you'd like.

 

[Robert Valentino]

I know this might be a little crazy but when having to do money math and want the remainder I would use longs or ints and multiple the number by 100

Dim Value1 As Int = 1300 ' $13.00
Dim Value2 As Int = 2
Dim Value3 As Int = Value1 / Value2
Dim Value4 As Int = Value3 / 100
Dim Value5 As Int = Value3 - (Value4 * 100)

Log(Value3) ' Amount
Log(Value4) ' Whole Dollars
Log(Value5) 'Cents

I'm sure not a good solution but will give you both answer and remainder in one variable

I'm sorry that I wrote the incorrect answer.
12\6=2 <---correctly, Get only integer number,(notget decimal number)
