I'm using "bc -l" either.

"-l" is including the math lib, for functions like exp, sin, cos, etc.

"bc" can calculate with arbitrary precision length.

Ever wanted to calculate with long, long numbers (i.e.: 2^256) or want to
edit a long input line (i.e.: 1.99*12+3*2.49+7*.79*1.16... ), then try it.

Best regards,
