binaryToDecimal64(float value);
----

== Description

Create a `Decimal64` object having the value closest to the specified `value` following the conversion rules as defined by IEEE‐754:

* If `value` is NaN, return a NaN. * Otherwise if `value` is infinity (positive or negative), then return an object equal to infinity with the same sign. * Otherwise if `value` is a zero value, then return an object equal to zero with the same sign. * Otherwise if `value` needs more than `std::numeric_limits<Decimal64>::max_digit` significant decimal digits to represent then return the `value` rounded according to the rounding direction. * Otherwise return a `Decimal64` object representing `value`.

== Return Value

closest 64‐bit decimal representation of `value`
