       <p>Numeric operators applied to mixed-type operands (such as a Number and a mathematical value) are not defined and should be considered an editorial error in this specification.</p>
       <p>This specification denotes most numeric values in base 10; it also uses numeric values of the form 0x followed by digits 0-9 or A-F as base-16 values.</p>
       <p>When the term <dfn id="integer" oldids="mathematical integer" variants="integers">integer</dfn> is used in this specification, it refers to a mathematical value which is in the set of integers, unless otherwise stated. When the term <dfn id="integral-number" variants="integral Numbers">integral Number</dfn> is used in this specification, it refers to a Number value whose mathematical value is in the set of integers.</p>

A conversion from an integer _x_ to a BigInt is denoted as "the BigInt value for _x_" or <dfn id="ℤ">ℤ</dfn>(_x_).
