Question

I am trying to read the values from excel sheet using java. When i type more than 10 letters in a cell in excel it is displaying in exponential form like \"9.78313E+2\". but

Answer 1

You can convert easily with the following methods:

Double.valueOf("9.78313E+2").longValue() or

BigDecimal bd = new BigDecimal("9.78313E+2");
long val = bd.longValue();

Assuming that the given number is in a String form.
