问题
I have a problem, for which there probably is an easy solution.
Suppose, I have calculated a large number in PARI/GP, lets say, 10,000 digits long.
I want to copy this number in a normal text file, such that it can be copied back to PARI/GP.
The problem is, that the program does not avoid (hidden) new-line-marks, so if I copy the number back, it cannot be read by PARI. The print1-command does not help either.
I had two non-satisfactionary ideas :
1) Copying in an editor, using the backspace-key to remove the (hidden) new-line-marks, which only works upto some length.
2) Extending the allowed length of a line, but then I cannot easily and fast mark the number, which is no problem with the normal lentgh 80.
How can I avoid the new-line-marks in the output in PARI/GP ?
回答1:
Piotr already gave the answer in a comment. Suppose you have:
n = 1<<33216
or any other number. Then if you use:
write("MySavedNumber.txt", n)
things will be fine. No new-lines in the middle of the text file.
When you need to recover the number in another session of PARI/GP, simply use:
n = read("MySavedNumber.txt")
