The java.math.BigDecimal.toBigInteger() is an inbuilt method in jav that converts this BigDecimal to a BigInteger. This conversion is analogous to the narrowing primitive conversion from double to long. Any fractional part of this BigDecimal will be discarded. This conversion can lose information about the precision of the BigDecimal value.
Note: If an exception thrown in the conversion inexact (in other words if a nonzero fractional part is discarded), use the toBigIntegerExact() method.
public BigInteger toBigInteger()
Parameters: This method does not accepts any parameters.
Return value: This method returns the value of BigDecimal object converted to a BigInteger.
Input: (BigDecimal) 123.321 Output: (BigInteger) 123 Input: (BigDecimal) 123.001 Output: (BigInteger) 123
Below programs illustrate the working of the above mentioned method:
BigInteger value of 123.321 is 123
BigInteger value of 123.001 is 123
