## How do you compare two BigInteger values?

compareTo(BigInteger value) method Compares this BigInteger with the BigInteger passed as the parameter.

- Syntax:
- Parameter: This method accepts a single mandatory parameter val which is the BigInteger to compare with BigInteger object.
- Returns: This method returns the following:
- Examples:

**How does BigInteger compare with BigInteger?**

for example: BigInteger reallyBig = BigInteger. valueOf(1); if(BigInteger….You can also compare two BigIntegers by using compareTo() method, as following: compareTo() returns 3 values.

- 0: When both are equal.
- 1: When first is greater than second (the one in brackets).
- -1: When first is less than second.

### How do I return BigInteger?

and(BigInteger val) method returns a BigInteger whose value is bitwise-AND of two BigIntegers. This method returns a negative number if both of the BigIntegers are negative.

**How do I check my BigInteger value?**

The java. math. BigInteger. signum() method helps us to identify whether a BigInteger is positive or zero or negative.

- returns -1 when number is negative.
- returns 0 when number is zero.
- returns +1 when number is positive.

#### 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 can I compare two BigDecimal values?**

compareTo(BigDecimal bg) method checks for equality of this BigDecimal and BigDecimal object bg passed as parameter. The method considers two equal BigDecimal objects even if they are equal in value irrespective of the scale.

## What is the use of compareTo method in Java?

Java String compareTo() The Java String class compareTo() method compares the given string with the current string lexicographically. It returns a positive number, negative number, or 0. It compares strings on the basis of the Unicode value of each character in the strings.

**How does Bigint compare to Java?**

BigInteger has a built-in static variable representing one. Use the equals() method or the compareTo() method to compare values: if (!a. equals(BigInteger.

### Is Java BigDecimal immutable?

Class BigDecimal. Immutable, arbitrary-precision signed decimal numbers. The value of the number represented by the BigDecimal is therefore (unscaledValue × 10-scale). The BigDecimal class provides operations for arithmetic, scale manipulation, rounding, comparison, hashing, and format conversion.

**What is BigInteger Signum?**

The signum() method of Java BigInteger class is used to check whether a BigInteger value is positive, negative or zero. This method returns 1 when this BigInteger is positive. This method returns 0 when this BigInteger is zero. This method returns -1 when this BigInteger is negative.
