The logarithmic integral function, denoted as \\( \\mathrm\{Li\}(x) \\), is a special function that is defined as follows: \\\[ \\mathrm\{Li\}(x) = \\int_2^x \\frac\{dt\}\{\\log(t)\} \\\] for \\( x > 1 \\). The function is often used in number theory, particularly in relation to the distribution of prime numbers.
