How do you convert Longinteger to Longinteger?

valueOf(long val) returns a BigInteger whose value is equal to that of the specified long. This “static factory method” is provided in preference to a (long) constructor because it allows for reuse of frequently used BigIntegers.

How do I convert to BigDecimal?

How do you convert big decimals to long?

longValue() is an in-built function which converts this BigDecimal to a long value. This function discards any fractional part of this BigDecimal. The function returns only the lower-order 64 bits when the result of the conversion is too big to be represented as a long value.
