In Ubuntu 14.04.1 LTS 64-bit bash I am declearing floating point variables by multiplying floating point bash variables in bc with scale set to 3; however, I cannot get the number of digits after the decimal point to be zero and get rid of the zero to the left of the decimal point. How can I transform, say 0.005000000 into .005? This is necessary due to my file naming convention. Thanks for your recommendations.

UPDATE: Can I use it for already defined shell variables and redefining them? The following code gives me an error.

~/Desktop/MEEP$ printf "%.3f\n" $w bash: printf: 0.005000: invalid number 0,000
