arithmetic operation on two columns
Hi, All,
I have a file, its content is as follows: 100 150 120 135 140 170 I want to insert a column, its content is determined by the difference between the two values in the same line, if the difference is less than 20, the new value is 1, otherwise is 0. after the operation, the file looks like 100 150 0 120 135 1 140 170 0 Could anybody help me out? Thanks in advance. Jenny |
