SciFloat2EStr Routines
Converts a Float into a string in Scientific Notation without Padding.

Unit
QESBPCSConvert

Overloaded Variants
Function SciFloat2EStr(const X: Extended; const Decimals: Byte = 4): string;
Function SciFloat2EStr(const X: Double; const Decimals: Byte = 4): string;
Function SciFloat2EStr(const X: Single; const Decimals: Byte = 4): string;

Declaration
Function SciFloat2EStr(const X: Extended; const Decimals: Byte = 4): string;

Description
This is of the form d.dddEnn. ESBBlankWhenZero can be set to True to have Zero returned as an Empty string, where Zero is dependent upon ESBTolerance.

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

          Exit;
     end;

     try
          Result := FloatToStrF (X, ffExponent, Decimals + 1, 0)
     except
          Result := '';
     end;
