This tutorial shows multiple ways to convert BigInteger to BigDecimal and BigInteger to BigDecimal in Java with examples using the BigDecimal constructor, using the toBigInteger method
public int longToIntBoxingValues(long number) { return Long.valueOf(number).intValue(); } 2.4. Using BigDecimal Moreover, we can accomplish this conversion using the BigDecimal class: public static int longToIntWithBigDecimal(long number) { return new BigDecimal(number).intValueExact(); } 2.5...
You can also use String’s ValueOf() method to convert BigDecimal to String but it internally uses BigDecimal’s toString method only, so it is better to use BigDecimal’s toString method 1 2 3 4 5 6 7 8 9 10 11 12 13 14 packageorg.arpit.java2blog; importjava.math.BigDecimal; publ...
