 * Implementation for Excel T.DIST.2T() function.
 * <p>
 * <b>Syntax</b>:<br> <b>T.DIST.2T </b>(<b>X</b>,<b>Deg_freedom</b>)<br>
 * <p>
 * Returns the two-tailed Student's t-distribution.
 * The Student's t-distribution is used in the hypothesis testing of small sample data sets.
 * Use this function in place of a table of critical values for the t-distribution.
 * <ul>
 *     <li>X     Required. The numeric value at which to evaluate the distribution.</li>
 *     <li>Deg_freedom     Required. An integer indicating the number of degrees of freedom.</li>
 * </ul>
 * <ul>
 *     <li>If any argument is non-numeric, T.DIST.2T returns the #VALUE! error value.</li>
 *     <li>If Deg_freedom &lt; 1, T.DIST.2T returns the #NUM! error value.</li>
 *     <li>If x &lt; 0, then T.DIST.2T returns the #NUM! error value.</li>
 *     <li>The Deg_freedom argument is truncated to an integer.
 * </ul>
