writing integers to a file in sml

Question

Is there a output in textIO signature to write integers to a file? output only writes vectors, outputsstring writes substrings and output1 writes only characters. My problem with not using vectors is I have to write each integer into a line in the output file.

I am having tough time with SML.

Thank You.

Do you want to write the integers to the files as bytes or as strings? — sepp2k, Oct 21 '12 at 16:22
Basically that does not matter. I have integers as input. I need to write them into file that's all. — 700resu, Oct 21 '12 at 16:40

To write an int to a file as a string, just convert it to a string using Int.toString and then write the string to the file.

To write a number to a file as a byte, use BinIO instead of TextIO. As the name suggests TextIO is for dealing with text - not binary data.

@user1710036 `output` takes a string. `TextIO.vector` is a type alias for `string`. – sepp2k Oct 21 '12 at 17:45
Thanks. it worked now. previously it showed somekind like mismatch of error. Its solved now. – 700resu Oct 21 '12 at 20:21
