     * {@link com.fasterxml.jackson.databind.node.DecimalNode} instances must be built with exact representations of
     * {@link java.math.BigDecimal} instances.</p>
     * <p/>
     * <p>This has quite an influence since, for instance, a BigDecimal (and,
     * therefore, a DecimalNode) constructed from input string {@code "1.0"} and
     * another constructed with input string {@code "1.00"} <b>will not</b> be
     * equal, since their scale differs (1 in the first case, 2 in the second
     * case).</p>
     * <p/>
     * <p>Note that setting the argument to {@code true} does <i>not</i>
     * guarantee a strict inequality between JSON representations: input texts
     * {@code "0.1"} and {@code "1e-1"}, for instance, yield two equivalent
     * BigDecimal instances since they have the same scale (1).</p>
     * <p/>
     * <p>The no-arg constructor (and the default {@link #instance}) calls this
     * constructor with {@code false} as an argument.</p>
