Sed/awk to find negative numbers and replace with 1?
Greetings. I have a three column file, and there are some numbers in the second column that are <1. However I need all numbers to be positive, thus need to replace all those numbers with just one. I feel like there must be a simple way to use awk to find these numbers and sed to replace but can't make it work.

Input:
Code:
3.894672	4221	4232
79.974159	-63	76
26.139051	1786	1798
30.866007	5045	5055
42.381535	-199	205
17.103092	-953	961
29.135157	1365	1384
29.135157	1643	1658

Desired Output:
Code:
3.894672	4221	4232
79.974159	1	76
26.139051	1786	1798
30.866007	5045	5055
42.381535	1	205
17.103092	1	961
29.135157	1365	1384
29.135157	1643	1658

Thanks!
