<div class="description">
    <p>The Number.isSafeInteger() method determines whether the provided value is a number that is a safe integer.
A safe integer is an integer that</p>
<ul>
<li>can be exactly represented as an IEEE-754 double precision number, and</li>
<li>whose IEEE-754 representation cannot be the result of rounding any other integer to fit the IEEE-754 representation.
For example, 2<sup>53</sup> - 1 is a safe integer: it can be exactly represented, and no other integer rounds to it under any IEEE-754 rounding mode.
In contrast, 2<sup>53</sup> is not a safe integer: it can be exactly represented in IEEE-754, but the integer 2<sup>53</sup> + 1 can't be directly represented in IEEE-754
but instead rounds to 2<sup>53</sup> under round-to-nearest and round-to-zero rounding.
The safe integers consist of all integers from -(2<sup>53</sup> - 1) inclusive to 2<sup>53</sup> - 1 inclusive.</li>
