Help with editing columns
Hi,

I have large file with 3 columns and want to output the 1st and 2nd column only. However I want the 2nd column to be edited like this: 14.036 to fx14 (notice the number in fx14 comes from the first two digits of 14.036)

BEFORE:
Code:
aran24352	14.036	14.036
aran08740	07.034	07.032
aran76153	17.199	17.197
aran76513	01.064	01.064
aran54894	04.209	04.207


AFTER:
Code:
aran24352	fx14
aran08740	fx07
aran76153	fx17
aran76513	fx01
aran54894	fx04

Could anyone help me please?
Thank you!
