BigInteger class is used for mathematical operation which involves very big integer calculations that are outside the limit of all available primitive data types. For example factorial of 100 contains 158 digits in it so we can’t store it in any primitive data type available. We can store as large Integer as we want in …

Java.math.BigInteger.toString() Method Advertisements Description The java.math.BigInteger.toString(int radix) returns the String representation of this BigInteger in the given radix. If the radix is outside the range from Character.MIN_RADIX to Character.MAX_RADIX inclusive, it will default to 10 (as is the case for Integer.toString). The digit-to-character mapping provided by Character.forDigit is used, and a minus sign is prepended …

Immutable arbitrary-precision integers. All operations behave as if BigIntegers were represented in two’s-complement notation (like Java’s primitive integer types). BigInteger provides analogues to all of Java’s primitive integer operators, and all relevant methods from java.lang.Math. Additionally, BigInteger provides operations for modular arithmetic, GCD calculation, primality testing, prime generation, bit manipulation, and a few other miscellaneous …

BigInteger class is used for the mathematical operation which involves very big integer calculations that are outside the limit of all available primitive data types. In this way, BigInteger class is very handy to use because of its large method library and it is also used a lot in competitive programming. Now below is given a …
