    Riemann Zeta Function Zeros Calculator.

    This program calculates the set \{a_N,...,a_M\}, where a_i is the imaginary part of the i-th root with a maximum error of ERROR.

    N is the position of the first root (must be a non-negative integer).

    M is the position of the last root (must be a non-negative integer greater than N).

    PREC is the width of the intervals where the existence of the roots is going to be examined (default_value=0.01) (must be a float geq 0).

    ERROR is the maximum error in the approximation of the roots (default_value=0.001) (must be a float geq 0).
