for evaluating functions by calculation

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Methods or arrangements for processing data by operating upon the order or content of the data handled > Methods or arrangements for performing computations using exclusively denominational number representation, e.g. using binary, ternary, decimal representation > using non-contact-making devices, e.g. tube, solid state device; using unspecified devices > for evaluating functions by calculation

CPC:

Methods or arrangements for processing data by operating upon the order or content of the data handled (logic circuits H03K19/00) > Methods or arrangements for performing computations using exclusively denominational number representation, e.g. using binary, ternary, decimal representation > using non-contact-making devices, e.g. tube, solid state device; using unspecified devices > for evaluating functions by calculation

Of 5 combined children, 3 exist in both systems.

2 codes are CPC-only extensions.

IPC defines codes here since 1980.
