Complete the code to output $\text{'}p=\text{'}$ followed by the value of $p$ to four digits after the decimal point. On the same line, output 'when $x=$ 'followed by the value of $x$ to one digit after the decimal point.

Ex: If the input is $1\mathrm{.}4,$ then the output is:

$p=2\mathrm{.}8000$ when $x=1\mathrm{.}4$

Note: $pr{\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}(f^{\text{'}}\{m{y}_f$loat: $xf{\}}^{\text{'}})$ outputs my$\_$float to $x$ digits after the decimal point.

$x=$ float $($input $()$
