printf format with awk

Shell Programming and Scripting

Hello
Here is an easy one

Data file

12345 (tab) Some text (tab) 53.432
23456 (tab) Some longer text (tab) 933.422
34567 (tab) Some different text (tab) 29.309

I need to awk these three tab-delimited columns so that the first two are unchanged (unformatted) and the third shows two decimal places:

Desired output

12345 (tab) Some text (tab) 53.43
23456 (tab) Some longer text (tab) 933.42
34567 (tab) Some different text (tab) 29.31

Thanks!

How about:

awk -F'\t' '{$3=sprintf("%.2f", $3)} 1' OFS='\t' infile
