Examples of java.math.BigDecimal.toBigIntegerExact()

java.math.BigDecimal.toBigIntegerExact()
Converts this {@code BigDecimal} to a {@code BigInteger}, checking for lost information. An exception is thrown if this {@code BigDecimal} has a nonzero fractional part. @return this {@code BigDecimal} converted to a {@code BigInteger}. @throws ArithmeticException if {@code this} has a nonzerofractional part. @since 1.5
