P2393 yyy loves Maths II

Last time, the noob (jǔruò) redbag made yyy very angry. yyy says he is only a primary school student, so the noob redbag will not trick him this time.

redbag gave yyy many numbers and asked yyy to compute their sum. It must be fast; redbag only gave yyy $1$ second.

One line with many numbers.

One line with a real number (rounded to $5$ decimal places), representing the sum of these numbers.

For $100\%$ of the testdata, each number is $\le 233,333,333$, there are at most $6$ digits after the decimal point, and there are at most $5\times 10^4$ numbers. Translated by ChatGPT 5
