FORMAT NUMBER WHILE PRINTING TO A TEXT FILE

[Rskm 0]

Hi, i have a variable (floating number - could be positive or negative), i wish to print it into a text file, how can i keep the format in such a way that it always has 4 digits ahead of decimal and 2 after decimal

basically i have total 7 columns in the text file to print the variable  ;

eg: variable = 1.235, output requied = 0001.24

variable=-23.55555, output required =-023.56

Check out

StringFormat

Hi , i am not able to fill in '0's ahead.. 

$num=1234.5656565

stringformat("%5.2f",$num) gives output as 1234.57, i need the result as 01234.57

That's not what you yourself wanted!

The output 01234.57 needs 8 "columns".

@jchd, i was taking a simple example with stringformat. All i want is that the cells should be occupied with zero if sufficient digits are not actually present in the number.. 

 

assuming 7 columns dedicated for printing, i expect 123.568 to be printed as 0123.57 and -1.2 to be printed as -001.20

This is the widest span you can process with 7 print positions:

Local $aPis = [ _
    -314.15926, _
     -31.415926, _
      -3.1415926, _
      -0.31415926, _
      -0.031415926, _
      -0.0031415926, _
      -0.00031415926, _
      -0.000031415926, _
       0.000031415926, _
       0.00031415926, _
       0.0031415926, _
       0.031415926, _
       0.31415926, _
       3.1415926, _
      31.415926, _
     314.15926, _
    3141.5926 _
]

For $f In $aPis
    ConsoleWrite(StringFormat("%07.2f", $f) & @LF)
Next

Mising required comma, sorry

You can combine the result.

Something like this?

$Start= 1234.5656565
MsgBox(4096,"",StringFormat("%05d", $Start ) & stringright(round($start - int($Start),2),3))

"Combining" this way doesn't work correctly and often produces wrong output:

Local $aPis = [ _
    -314.15926, _
     -31.415926, _
      -3.1415926, _
      -0.31415926, _
      -0.031415926, _
      -0.0031415926, _
      -0.00031415926, _
      -0.000031415926, _
       0.000031415926, _
       0.00031415926, _
       0.0031415926, _
       0.031415926, _
       0.31415926, _
       3.1415926, _
      31.415926, _
     314.15926, _
    3141.5926 _
]

For $f In $aPis
    ConsoleWrite(StringFormat("%07.2f", $f) & " =?= " & StringFormat("%04d", $f ) & StringRight(Round($f - Int($f),2),3) & @LF)
Next

It looks pretty good If you us an if to solve the Zero answers?

[jchd 1,544]

You didn't:

-314.16 =?= -314.16
-031.42 =?= -031.42
-003.14 =?= -003.14
-000.31 =?= 0000.31    Wrong
-000.03 =?= 0000.03    Wrong
-000.00 =?= 0000-0     Non-sensical & format violation
-000.00 =?= 0000-0     Non-sensical & format violation
-000.00 =?= 0000-0     Non-sensical & format violation
0000.00 =?= 00000      Format violation
0000.00 =?= 00000      Format violation
0000.00 =?= 00000      Format violation
0000.03 =?= 0000.03
0000.31 =?= 0000.31
0003.14 =?= 0003.14
0031.42 =?= 0031.42
0314.16 =?= 0314.16
3141.59 =?= 3141.59

I still don't get how a much more convoluted approach using several function calls and conditionals is better than a single plain StringFormat.

Anyway feel free to post your fixed alternative solution.

Depending what Rskm wants in his text file?

Local $aPis = [ _
         - 314.15926, _
         - 31.415926, _
         - 3.1415926, _
         - 0.31415926, _
         - 0.031415926, _
         - 0.0031415926, _
         - 0.00031415926, _
         - 0.000031415926, _
        0.000031415926, _

        31.415926, _
        314.15926, _
        3141.5926 _
        ]

For $f In $aPis
    If Round($f, 2) = 0 Then
        ConsoleWrite("00000.00" & @lf)
    Else
        ConsoleWrite(StringFormat("%05d", $f) & StringRight(Round($f - Int($f), 2), 3) & @LF)
    EndIf
Next

He said he need to fill a 7-char field with always 2 decimals.

Your code still fails on integers:

Local $aPis = [ _
    -314.15926, _
     -31.415926, _
      -3.1415926, _
      -0.31415926, _
      -0.031415926, _
      -0.0031415926, _
      -0.00031415926, _
      -0.000031415926, _
       0.000031415926, _
       0.00031415926, _
       0.0031415926, _
       0.031415926, _
       0.31415926, _
       3.1415926, _
      31.415926, _
     314.15926, _
    3141.5926, _
    -1234, _
    -123, _
     -12, _
      -1, _
       1, _
      12, _
     123, _
    1234, _
    12345 _
]

For $f In $aPis
    If Round($f, 2) = 0 Then
        ConsoleWrite("00000.00" & @lf)
    Else
        ConsoleWrite(StringFormat("%05d", $f) & StringRight(Round($f - Int($f), 2), 3) & @LF)
    EndIf
Next

Yes I saw the 7 and also your comment on 8 columns.

But any way, an even more convoluted approach?

Local $aPis = [ _
         - 314.15926, _
         - 31.415926, _
         - 3.1415926, _
         - 0.31415926, _
         - 0.031415926, _
         - 0.0031415926, _
         - 0.00031415926, _
         - 0.000031415926, _
        0.000031415926, _
        0.00031415926, _
        0.0031415926, _
        0.031415926, _
        0.31415926, _
        3.1415926, _
        31.415926, _
        314.15926, _
        3141.5926, _
         - 1234, _
         - 123, _
         - 12, _
         - 1, _
        1, _
        12, _
        123, _
        1234, _
        12345 _
        ]

For $f In $aPis
    If Round($f, 2) = 0 Then
        ConsoleWrite("00000.00" & @LF)
    Else
        ConsoleWrite(StringFormat("%05d", $f) & StringRight(StringFormat("%.2f", $F), 3) & @LF)
    EndIf
Next

 

[jchd 1,544]

That was my point: in such cases, StringFormat is both more robust, versatile and less error-prone than a more pedestrian approach.
