Summary
A straightforward arbitrary-precision calculator that handles the math expressions you throw at it without floating-point nonsense. Built on big.js, so 0.1 + 0.2 actually equals 0.3 like it should. Supports the standard operators plus exponents (right-associative, integers only), respects precedence, and handles parentheses correctly. You call it from the command line with an expression string and get a result back. The limitation list is honest: no trig functions, no variables, no modulo. It does one thing well, which is evaluate basic arithmetic precisely. Good for when you need Claude to crunch numbers in financial contexts or anywhere decimal accuracy matters more than scientific computing features.
