A large number is represented as:
number_of_digits(total) number_of_digits sign digits' list
E.g.: -45567.56 will be represented as:
7 5 1 4 5 5 6 7 5 6
Zero will be represented as a single one-line "0". The included procedures can compute addition / substraction / multiplication with scalar / multiplication between integer large numbers. Divqr computes quotient and remainder of division. I also included scripts for division with two decimals in the result and square root with two decimals (by truncation). The scripts do not validate inputs as far as I remember. There are also included two python scripts, one for generating input files and one for testing purposes by comparing different outputs with the ones provided.
