First, read the first floating$-$point number from input. Then, read the remaining floating$-$point numbers while the floating$-$point numbers are in the range $-40\mathrm{.}0$ to $40\mathrm{.}0,$ both exclusive. Next, find the sum of the floating$-$point numbers that are in the given range. Lastly, output the sum, ending with a newline.

Ex: If the input is $-37\mathrm{.}9-36\mathrm{.}2-44\mathrm{.}4-33\mathrm{.}3,$ then the output is:

$-74\mathrm{.}1$

Note: $-40\mathrm{.}0$ and $40\mathrm{.}0$ are not in the given range.
