Class funct_multip_string_tl (o2scl)¶

template<class fp_25_t, class fp_35_t, class fp_50_t, class fp_100_t> class funct_multip_string_tl¶

Evaluate a one-dimensional function from a string at multiprecision using the internal constant library.

Warning

This class only supports a limited number of data types, including double, long double, and cpp_dec_float or mpfr types with 25, 35, 50, or 100 digits. It is designed to be used with the funct_multip class.
