 * Function:    H5Tget_precision

 *

 * Purpose: Gets the precision of a datatype.  The precision is

 *      the number of significant bits which, unless padding is

 *      present, is 8 times larger than the value returned by

 *      H5Tget_size().

 *

 * Return:  Success:    Number of significant bits

 *

 *      Failure:    0 (all atomic types have at least one

 *              significant bit)
