How do I display a large number in scientific notation?

Using AutoIt, when I multiply 1 by 10^21, I get 1e+021. But in separate steps, such as multiplying 1 by 10^3 seven times, I get the overflow value of 3875820019684212736.

It appears AutoIt cannot handle numbers with more than eighteen digits. Is there a way around this? For example, can I multiply 10,000,000,000,000,000 by 1000 and have the result displayed as 1e+019?

Solution

  • Try this UDF : BigNum UDF

    Example : 

    $X = "9999999999999999999999999999999"
$Y = "9999999999999999999999999999999"
$product = _BigNum_Mul($X, $Y)
