# Calculate average, total and the biggest - from array

## Recommended Posts

Hello,

I have a listview and I converted the values from it in a 2D array and I need to calculate average, total and the biggest of the data from one column.

the 2d array is named \$lt1

\$lt1[0][0] = is the number of rows (how many values I have) This number will change so one time \$lt1[0][0]  is 10 for ex, another time \$lt1[0][0]  is 4 or can be any number. The number of elements is not exact (n+1)

my values are in \$lt1[1 to n+1][12]

So I need to calculate the average for the number \$lt1[1][12], \$lt1[2][12], \$lt1[3][12], \$lt1[n+1][12] .

How I can do this please?

Maybe:

```Local \$average
For \$n = 1 To \$lt1[0][0]
\$average += \$lt1[\$n][12]
Next
\$average = \$average / \$lt1[0][0]```

4

```Local \$average
For \$n = 1 To 4
\$average += \$lt1[\$n][12]
Next
\$average = \$average / 4```

For the average is ok, but how I can calculate de maximum value that is in the array and the sum ?

Within the same loop:

```Local \$average, \$total, \$max
For \$n = 1 To \$lt1[0][0]
\$average += \$lt1[\$n][12]
\$total += \$lt1[\$n][12]
If \$lt1[\$n][12] > \$max Then \$max = \$lt1[\$n][12]
Next
\$average = \$average / \$lt1[0][0]```

```Local \$average, \$BigVar = 0
For \$n = 1 To \$lt1[0][0]
If \$lt1[\$n][12] > \$BigVar Then \$BigVar = \$lt1[\$n][12]
\$average += \$lt1[\$n][12]

Next
\$average = \$average / \$lt1[0][0]
ConsoleWrite("! Average: " & \$average & @CRLF)
ConsoleWrite("! Bigger Number: " & \$BigVar & @CRLF)```

Hello guys,

I tried both script but no one is working correct when calculating the maximum value from the array.

So I have this values:

0

0

0

0

3

0

6

0

0

144

Average value is: 15.3

Big value is: 6

Total 153

Why big value is 6 and not 144?

I used this code:

```\$lt1 = _GUIListViewEx_ReadToArray(\$listatickete, 1)
_ArrayDisplay(\$lt1, "1D display")

Local \$average, \$total, \$max
For \$n = 1 To \$lt1[0][0]
\$average += \$lt1[\$n][14]
\$total += \$lt1[\$n][14]
If \$lt1[\$n][14] > \$max Then \$max = \$lt1[\$n][14]
Next
\$average = \$average / \$lt1[0][0]

Msgbox (0, "average", \$average)
Msgbox (0, "bigvar", \$max)
Msgbox (0, "total", \$total)```

Probably because you've stored your values as strings and not integers or reals.

and how i can convert them to integers? I take the data from a listview

This detail was omitted from the OP. Try this:

```Local \$average, \$total, \$max
For \$n = 1 To \$lt1[0][0]
\$average += \$lt1[\$n][12]
\$total += \$lt1[\$n][12]
If Number(\$lt1[\$n][12]) > \$max Then \$max = Number(\$lt1[\$n][12])
Next
\$average = \$average / \$lt1[0][0]```
