Examples of java.math.BigDecimal.longValue()

java.math.BigDecimal.longValue()
sun.com/docs/books/jls/second_edition/html/conversions.doc.html#25363">narrowing primitive conversion from {@code double} to{@code short} as defined in the Java Language Specification: any fractional part of this {@code BigDecimal} will be discarded, and if the resulting" {@code BigInteger}" is too big to fit in a {@code long}, only the low-order 64 bits are returned. Note that this conversion can lose information about the overall magnitude and precision of this {@code BigDecimal} value as wellas return a result with the opposite sign. @return this {@code BigDecimal} converted to a {@code long}.
