Long non-negative integer non-template class. Such a number is analogous to unsigned int, but it can have an unlimited number of digits in advance.
The class has the following list of operations:
- explicit construction from a decimal string (std :: string).
- copying
- explicit conversions to an integer (uint32_t). If the number does not fit in uint32_t, the value is narrowed (like int -> short)
- the ability to use in conditional expressions
- the class should not allow subtraction
- function to get the decimal string representation to_string
- input/output to standard streams
- operations +, *, +=, *=
Implements polynomial abstraction
The class has the following list of operations:
- explicit constructor from the format string:
5*x^3+2*x^1+6*x^0(no whitespace characters, the degree is always specified, the coefficient may be absent) - "at" functions (constant and non-constant) for accessing the coefficient of a polynomial by index
- operator "()" for calculating a polynomial at a point (implemented using Horner's scheme)
