Lib.rs

This is a simple command line app that acts as a scientific calculator, operating through commands instead of buttons.

For now, only one operation may be performed at a time. However, this will be updated soon so that multiple operations can be performed through a single line!

Commands

For detailed directions on the command line: cargo run calculator -h

Addition (--plus or -p)

cargo run [base_number] --plus [addend] Eg. cargo run 10 --plus 10 will result in 20.

Subtraction (--subtract-by or -s)

cargo run [base_number] --subtract-by [subtrahend] Eg. cargo run 10 --subtract-by 8 will result in 2.

Multiplication (--multiply-by or -m)

cargo run [base_number] --multiply-by [multiplier] Eg. cargo run 10 --multiply-by 2 will result in 20.

Division (--divide-by or -d)

cargo run [base_number] --divide-by [divisor] Eg. cargo run 10 --divide-by 5 will result in 2.

Exponentiation (--exponent or -x)

cargo run [base_number] --exponent [exponent] Eg. cargo run 10 --exponent 2 will result in 100.

Radical Operation (--root or -r)

cargo run [base_number] --root [root] Eg. cargo run 100 --root 2 will result in 10.

Logarithm (--log or -l)

cargo run [base_number] --log [base] Eg. cargo run 100 --log 10 will result in 2.

Trigonometry

All base numbers must be in radians.
