Instead of having to write: `csdr shift_addition_cc $(python -c "print 1200/2400000.")` Instead of having to write:
...we can type: `csdr shift_addition_cc $(csdr =1200/2400000.)` csdr shift_addition_cc $(python -c "print 1200/2400000.")
If using parenthesis inside the expression, it needs to be escaped (as `bash` would want to parse it): `csdr shift_addition_cc $(csdr =\(1200+300\)/2400000)` ...we can type:
