Hi there,

I’m trying to solve project euler #13 in julia. I have to give the first 10 digits of a humongous integer.

To obtain that integer, I have to read line by line a file with really big integers and summing them up. The solution will be the first ten digits of that integer.

I could sum them up but I’m getting troubles when parsing it. This part reads the file and calculate the result as a float:

```
using DoubleFloats
result = sum(parse.(Double64, readlines("my_file.txt")))
```

but the result is printed as “5.5373762303908766373020487468328705e+51”. If I try to parse it to a “BigInt” I get the following error:

`ERROR: LoadError: MethodError: no method matching parse(::Type{BigInt}, ::Double64)`

How can I get the first 10 digits of that big integer?

Thanks in advance

*“my_file.txt” has 100 big integers such as this one: 37107287533902102798797998220837590246510135740250

Each of these integers is in a new line without \n to separate them.
