Complete the code to output $\text{'}$k $=\text{'}$ followed by the value of k to four digits after the decimal point. On the same line, output $\text{'}$ when v $=\text{'}$ followed by the value of v to three digits after the decimal point.

Ex: If the input is $3\mathrm{.}500,$ then the output is:

k $=14\mathrm{.}0000$ when v $=3\mathrm{.}500$
