Hi,
I am trying to convert a String with value as 00000101001 to BigDecimal.
Just using the below code:
String str="00000101001 ";
BigDecimal bd= new BigDecimal (str);
after conversion to BigDecimal i am getting the value as 101001.
How can i get the exact String 00000101001 converted to BigDecimal.

Actual numbers -- whether they are BigDecmials, ints, longs, floats, bytes, or what-have-you -- never include leading zeros. They have no particular format at all: they represent an abstract mathematical concept. If you want to display leading zeros, you have to provide them yourself.

(Note that in Java, if you write an integer literal with a leading 0, it's assumed to be a number in octal (base 8!))

In which case a look at the BigInteger constructors might be helpful. Note that is BigInteger, not BigDecimal, but the String you quoted is an integer.
