Is there anyway to convert from double
value to BigInteger
?
double doubleValue = 64654679846513164.2;
BigInteger bigInteger = (BigInteger) doubleValue;
I try to cast it but it didn't work.
3. BigInteger Larger Than Long. MAX_VALUE. As we already know, the long data type is a 64-bit two's complement integer.
If you want to store the integral part of the double into a BigInteger
, then you can convert it into a BigDecimal
and then into a BigInteger
:
BigInteger k = BigDecimal.valueOf(doubleValue).toBigInteger();
BigInteger is made for holding arbitrary precision integer numbers, not decimals. You can use the BigDecimal
class to hold a double.
BigDecimal k = BigDecimal.valueOf(doublevalue);
In general, you cannot type cast a Java primitive into another class. The exceptions that I know about are the classes extending Number
, such as the Long
and Integer
wrapper classes, which allow you to cast an int value into an Integer, and so on.
