Complete the code to output $"$k $="$ followed by the value of k to three digits after the decimal point. On the same line, output $"$ when w $="$ followed by the value of w to two digits after the decimal point. End with a newline.

Ex: If the input is $1\mathrm{.}20,$ then the output is:

k $=-0\mathrm{.}100$ when w $=1\mathrm{.}20$
