+{% capture summary %}
 The `{{page.slug}}` format represents a [128-bit decimal floating-point number](https://en.wikipedia.org/wiki/Decimal128_floating-point_format) as defined by IEEE 754 2008 and ISO/IEC/IEEE 60559:2011.
 
 Representation as a JSON string is preferred as this avoids problems with recipients that parse JSON numbers into [binary64](https://en.wikipedia.org/wiki/Double-precision_floating-point_format) memory representation.
 
 String representation allows expressing the special values `NaN`, `-INF`, and `INF` that cannot be expressed as JSON numbers.
