Usage of BC

BC is an arbitrary precision calculator language, that is, an arbitrary precision computing language, attention is a language, it provides some grammatical structure, such as conditional judgment, circulation, etc., can be said to be very powerful, But I haven't found a place to use it in practice. Another use is for the conversion of the binary.

Common parameters:

-Q does not output hints

-l transfer into math library

Instance:

A) command line mode (Python-like interpreter):

b) echo Pipe mode:

1, calculate 2 of 10 square: echo "2^10" |BC

2, calculate 1 divided by 27, and retain 10 decimal places: Echo "Scale=10;1/27" | Bc

c) in-process conversion
1) binary 10011011 turns into decimal: echo "ibase=2;10011011" |BC

2) Enter decimal 10000 into octal: echo "obase=8;10000" |BC
