Purpose
You want to convert a floating point number to decimal

Some SAP tables contain values in floating point format. When you read such tables with; for example, /guixt/dbselect, a number in floating point notation is returned, e.g.  "1.5301000000000000E+03"  or with a comma as decimal separator 
"1,5301800000000000E+03".  For further calculations and comparisons in GuiXT you need the decimal representation of the number.
 

Solution
Use the JavaScript toFixed() funcion.

The following utility function returns the decimal format of a given number in floating point format. You may sepecify a fixed number of decimal places as a second argument.

// convert a number from floating point format to decimal format
// option: specify fixed number of decimals
function Float2Dec(x,fixdec)
{

   var deccomma =x.indexOf(',') > -1;
   if (deccomma)
   {
     x = x.replace(",", ".");
   }; 

   if (isNaN(parseFloat(x))) 
   {
    return 0;
   }

   
  var result; 
  if (fixdec)
  {
    result = parseFloat(x).toFixed(fixdec);
  }
  else 
  {
    result = parseFloat(parseFloat(x).toFixed(8)).toString() ;
  };

  
   
   if (deccomma)
   {
     result= result.replace(".", ",");
   }; 

   return result; 
};


Examples

Set V[f1] "1.5301800000000000E+03"
CallJS f2 = Float2Dec &V[f1]
 
 // Test message
 Message "&V[f2]"





Set V[f1] "1.5301800000000000E+03"
CallJS f2 = Float2Dec &V[f1] 1
...




Set V[f1] "1.5301800000000000E+03"
CallJS f2 = Float2Dec &V[f1] 5
...





Set V[f1] "1.5301805600E+03"
CallJS f2 = Float2Dec &V[f1]
...
