Scala Converting multiline string to BigInt

Question

I\'m trying to parse 100 50-digit numbers from string with below piece of code:

val input = \"\"\"37107287533902102798797998220837590246510135740250
                 


        

Answer 1

Probably you're on Windows, where the EOL is \r\n.

You've got to strip that, too.

Here, I rebooted into Windows to demo...

apm@halyard ~/tmp
$ vi bigbomb.scala

apm@halyard ~/tmp
$ skalac bigbomb.scala ; skala bigbomb.Test
"ava.lang.NumberFormatException: For input string: "35740250
        at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)

Note that in cygwin, I have to :se fileformat=dos in vi to use the \r\n line endings.

Here is an example where the unacknowledged impedance mismatch between the source EOL and the runtime EOL bugged me:

some dumb code

You want to use s.lines.mkString to strip it out.
