What value will $z$ have if we execute the following assignment statement?float $z=\frac{5}{10}$;

$z$ will equal $0\mathrm{.}0$

z will equal $0\mathrm{.}5$

z will equal $5\mathrm{.}0$

z will equal $0\mathrm{.}05$

none of the above; a run$-$time error arises because $z$ is a float and $\frac{5}{10}$ is an int
