Shell Programming and Scripting

Hi Gurus,

I'm currently using HP-UX B.11.23.

I've a simple calculation script which performs the task below.

-> echo "240021344 / 1024 /1024" | bc
Output: 228

240021344 is KB value.

When I tried to perform the same calculate in Ms Excel, it produces a different result: 228.9021912.

Is it possible to perform this calculation and generate this output: 228.90 (2 decimal formats) ?

Would appreciate for any of your advice and help.

Thanks.

Peter

Hi.

Try:

Code:

$ echo "scale=2; 240021344 / 1024 /1024" | bc
228.90

Hi scottn,

Thank you for your response.

I've tried your method and it's working on a bigger figure and having figure with smaller value as shown below:

Code:

echo "scale=2; 240021344 / 1024 /1024" | bc

Output: 228.90

Code:

echo "scale=2; 130256/ 1024 / 1024" | bc

Output: .12
-> Should be: 0.12

Code:

echo "scale=2; 1043064 / 1024 / 1024" | bc

Output: .99
-> Should be: 0.99

Are you able to advice on this issue?

Thanks a lot.



Regards,

Code:

awk '{ printf("%.2f\n", ( 130256 / 1024 / 1024) ) }'

Hi busyboy,

Thanks for your repsonse.

However, when I tried your method, it does not show anything.

Code:

awk '{ printf("%.2f\n", ( 130256 / 1024 / 1024) ) }'

Is there something wrong?

Please kindly advice.

Thanks.

Hi, you need the BEGIN tag:

Code:

 awk 'BEGIN{ printf("%.2f\n", ( 130256 / 1024 / 1024) ) }'

Should be:

Code:

awk 'BEGIN{printf("%.2f\n", 130256 / 1024 / 1024)}'

or:

Code:

echo "130256 1024 1024" | awk '{ printf("%.2f\n", $1 / $2 / $3)}'
