$1.$ Report the result in the scientific format using $2$ decimal places, employ chopping, and show trailing and leading zeroes $($As in $0\mathrm{.}40$e$-02,$ not $\mathrm{.}4$e$-02)$

$2.$ Any number with trailing zeroes should be reported with the trailing zeroes, i$.$e$.$ if the answer is exactly $4\mathrm{.}5$e$+00,$ then report it as $4\mathrm{.}50$e$+00.$

$3.$ If the value is positive, for example, $4\mathrm{.}5347$e$+10,$ then report it as $4\mathrm{.}53$e$+10.$

$4.$ If the value is negative, for example, $-4\mathrm{.}5347$e$+10,$ then report it as $-4\mathrm{.}53$e$+10($do not leave a space between the negative sign and the reported value$)$

$5.$ For the exponential part, also report the sign and two numbers of power $($e$-05$ or e$+03)$; if the power is zero, the sign would be positive $($e$+00).$
