scientific notation to expanded form ?

4 posts in this topic

im writing a simple internal data compressor which uses the ANSI charecter codes and converts them into a large integer which is then divided by a number (based on the compression level) the problem is that when the data is decompressed it hase to times the integer by the divided number, but the number returned 4.36484128440388e+039 how can i convert it to its expanded form (109121032110097109101032105115032098111098)

#include <array.au3>
 

Func _decompressdata($data,$level)
$idata = _StringCut($data*$level,3)
Local $chr
For $i = 0 to UBound($idata) -1
$chr &= Chr($idata[$i])
Next
Return $chr
endFunc
Func _StringCut($string, $size)
$count = Ceiling(StringLen($string)/$size)
Dim $array[$count+1], $start = 1
For $i = 1 To $count
    $array[$i] = StringMid($string, $start, $size)
    $start += $size
Next
$array[0] = $count
_ArrayDelete($array,0)
Return $array
EndFunc

Large Numbers...

I guess you have to check BigNum UDF for handling them.

What I mean ? Check this

$String = '109121032110097109101032105115032098111098'
;see the difference.
MsgBox(64, "String", $String)
MsgBox(64, "Number", Number($String))

According to what you are asking, string operations could be used to get back the original expression, but the number could not be used in any calculations through native methods.


My code:

PredictText: Predict Text of an Edit Control Like Scite. Remote Gmail: Execute your Scripts through Gmail. StringRegExp:Share and learn RegExp.

Run As System: A command line wrapper around PSEXEC.exe to execute your apps scripts as System (LSA). Database: An easier approach for _SQ_LITE beginners.

MathsEx: A UDF for Fractions and LCM, GCF/HCF. FloatingText: An UDF for make your text floating. Clipboard Extendor: A clipboard monitoring tool. 

Custom ScrollBar: Scroll Bar made with GDI+, user can use bitmaps instead. RestrictEdit_SRE: Restrict text in an Edit Control through a Regular Expression.

I never knew the largest possible number available was 9223372036854775807. Still a big number though.

This way you can convert the expression into numerical form

MsgBox(64, "Return", String_Expand_E_Notation("4892e-32"))
MsgBox(64, "Return", String_Expand_E_Notation("4892E213"))

Func String_Expand_E_Notation($s_integer)

    StringRegExpReplace($s_integer, "(?i)[^e\d.+\-*/^]", "")
    ;anything other than "e", digit, operators and decimal is found.
    If @extended Then Return SetError(1, @extended, 0)

    ;perform the replacement and return the result.
    Return StringRegExpReplace($s_integer, "(?i)(e([+\-]?[\d.]+)$)", "*(10^(\2))")

EndFunc   ;==>String_Expand_E_Notation

 

use the BigNum UDF to get the real number thereafter

Regards :)
