Rust Simple Calculator

Simple calculator written in Rust. Supports many arithmetic functions, boolean logic, and builtin functions.

Value types

The calculator supports four value types:

Booleans (true and false)
Numbers (examples: 1, 3.2, -200, 1.3333, 1e-3, 0xFFFFF, 0b010011, 0o777)
- number support radix 2 (binary), 8 (octal), and 16 (hex)

Supports the following operations:

Arithmetic
- Addition: a + b
- Subtraction: a - b
- Multiplication: a * b
- Division: a / b
- Rem / Module: a % b
- BitAnd: a & b
- BitOr: a | b
- BitXor: a ^ b
- Shr: a >> b
- Shl: a << b
Relational
- Equal: a == b, a != b
- Compare: a < b, a <= b, a > b, a >= b
Logic
- Conjunction: a and b
- Disjunction: a or b
- Negation: not a

[] Supports the following constants.
- pi
- tau
- e
- nan
- inf
- neginf
[] The following common mathematical functions are supported.
- sin(x), cos(x), tan(x)
- asin(x), acos(x), atan(x)
- ln(x), log10(x), log2(x), log(x, base)
- round(x), floor(x), ceil(x)
- sqrt(x), exp(x), powf(x, e), pow(x, e)
- abs(x), min_num(x, y), max_num(x, y)
[] The following Python-like utility functions are included.
- min(...): minimum of arguments.
- max(...): maximum of arguments.
- rand(), rand(stop), rand(start, stop): random float (default range is 0.0 to 1.0).
[] The following common printing functions to stdout/stderr are supported.
- print(value): print to stdout
- println(value): print to stdout with new line at the end
- eprint(value): print to stderr
- eprintln(value): print to stderr with new line at the end
- debug(expr): print debug representation for expression
[] The following common format number functions.
- bin(value, _bool): format number as string in binary format (0b111)
- oct(value, _bool): format number as string in octal format (0o777)
- hex(value, _bool): format number as string in hex format (0xFFF)
