java.math.BigInteger.floatValue()
sun.com/docs/books/jls/second_edition/html/conversions.doc.html#25363">narrowing primitive conversion from {@code double} to{@code float} defined in the Java Language Specification: if this BigInteger has too great a magnitude to represent as a {@code float}, it will be converted to {@link Float#NEGATIVE_INFINITY} or {@link Float#POSITIVE_INFINITY} as appropriate. Note that even whenthe return value is finite, this conversion can lose information about the precision of the BigInteger value. @return this BigInteger converted to a {@code float}.
