Examples of java.math.BigDecimal.toBigInteger()

java.math.BigDecimal.toBigInteger()
sun.com/docs/books/jls/second_edition/html/conversions.doc.html#25363">narrowing primitive conversion from {@code double} to{@code long} as defined in the Java Language Specification: any fractional part of this {@code BigDecimal} will be discarded. Note that thisconversion can lose information about the precision of the {@code BigDecimal} value.
To have an exception thrown if the conversion is inexact (in other words if a nonzero fractional part is discarded), use the {@link #toBigIntegerExact()} method. @return this {@code BigDecimal} converted to a {@code BigInteger}.
