 The `{{page.slug}}` format represents an integer that can be stored in an IEEE 754 double-precision number without loss of precision. The range of values is -(2<sup>53</sup>)+1 to (2<sup>53</sup>)-1.
 
 This format is useful for systems that need to support languages (such as JavaScript) that store all numeric values as IEEE 754 double-precision numbers.
