Not sure, but I'm unable to get this.
38/1024 = 0.0371
When i'm performing:
echo "scale=2; 15 / 0.0371" |bc, it gives me result:
404.31
But, when i', performing :
echo 'scale=2; 15/(38/1024)' |bc , the output is:
500.00
Why there's difference in results.
I need the output to be 404.31 from the second command.
Thanks.
This is because your floating point precision is different in second case.
In first case you are using 0.0371 for division whereas in second case you are using 38/1024 with precision for 2 decimal points which gives 0.03.
So essentially your actual command in second case is
echo "scale=2; 15 / 0.03" |bc
hence different output.
If you want the same output as first use scale as 4 like
echo "scale=4; 15/(38/1024)" |bc
