FAQ

Questions currency.js owners ask.

  • 01

    Why can't the LLM do this math?

    LLMs predict the next logical token; they don't use internal ALU processors for math. This leads to hallucinations in complex decimal arithmetic.

  • 02

    Does it support different currencies?

    Yes, it handles any currency format seamlessly by focusing strictly on the numerical value representation.

  • 03

    What operations are supported?

    Addition, subtraction, multiplication, and division.
