Float2EStr Routines
Converts a Float into a string without Padding.

Unit
QESBPCSConvert

Overloaded Variants
Function Float2EStr(const X: Extended; const Decimals: Byte = 4): string;
Function Float2EStr(const X: Double; const Decimals: Byte = 4): string;
Function Float2EStr(const X: Single; const Decimals: Byte = 4): string;

Declaration
Function Float2EStr(const X: Extended; const Decimals: Byte = 4): string;

Description
ESBNumPosSign controls whether a '+' Sign appears at the beginning for positive Integers. ESBBlankWhenZero can be set to True to have Zero returned as an Empty string, where Zero is dependent upon ESBTolerance. Also see Float2EStr2, Float2Str & Float2CEStr

Parameters
Value to Convert to String.
Decimals is the desired number of Decimal places, defaults to 4

Implementation

function Float2EStr (const X: Extended; const Decimals: Byte = 4): string;
begin
     if ESBBlankWhenZero and FloatIsZero (X) then
     begin
          Result := '';
          Exit;
     end;

     try
          Result := FloatToStrF (X, ffFixed, 18, Decimals);

          if ESBNumPosSign and (X > 0) then // See if '+' needed
               Result := '+' + Result;
     except
          Result := '';
     end;
End;
