Public Shared Function x02aj As Double

public:
static double x02aj()

static member x02aj : unit -> float 

x02aj returns $\epsilon$, the value machine precision.

x02aj returns machine precision, computed as $\epsilon =\frac{1}{2}\times b^{1-p}$, where $b$ is the arithmetic base (see x02bh) and $p$ is the number of significant base-$b$ digits (see (X02BJF not in this release)).

It is important to note that the definition of $\epsilon$ here differs from that in ISO (1997).
