[Lazarus] JSON float saving scientific value

[tcoq]

Indeed, the localization is an issue, but it is possible to force FloatToStr to output a decimal '.' in all cases, whatever the localization. Isn't it 
DecimalSeparator? Change DecimalSeparator to '.'. 
Something like this (untested/uncompiled pseudo-code):

Function FloatToStrMine( aNumber: Double): String;
var
  oldDecimal: Char;
begin
  oldDecimal := DecimalSeparator;
  DecimalSeparator := '.';
  try
    result := FloatToStr( aNumber)
  finally
    DecimalSeparator := oldDecimal;
  end;
end;

Best regards,
Thierry

You should definitely not do that, because then the resulting string is localized. 
JSON is not localized. It MUST use a . as the decimal separator.
