Good afternoon,

I would like to place a question here. I want to convert a decimal number to the scientific notation. I made the following routine, but it truncates the decimals:

sub dec2eng {
($mydecimal)=@_;
$myscience = sprintf("%e", $mydecimal);
return $myscience;
}

For instance: the decimal number 0.99982928833 is converted to 9.998293e-001 - the number is rounded, and so I loose 5 decimals (28833).

Is there a way to do this calculation without recurring to outside perl modules?

Kind regards, Kepler
