Class funct_multip_string (o2scl)¶
-
class funct_multip_string¶
Evaluate a one-dimensional function from a string at multiprecision.
Note
Experimental.
Warning
This class only supports a limited number of data types, including double, long double, and cpp_dec_float types with 25, 35, 50, or 100 digits. It is designed to be used with the funct_multip class.
