I am using bc function in my bash script for simple arithmetic expressions on fractional numbers
c_mod='2.44'
RG_mod='0.55'
c_final=$(echo "$c_mod + $RG_mod" | bc)
This gives me correct value of the c_final = 2.99
cl_tol=$(echo "$c_final * 0.1" | bc)
But in this case cl_tol= .29 (not 0.29) how I may add zero in the last case ?
