Note on Software III. Interpreter MACRO/2 and MACRO/3

MINI has no floating point arithmetic unit and we developed the interpreters MACRO/2 and MACRO/3, by which floating point arithmetic could be performed, for MINI. The determination of the effective address in the language interpreted by these interpreters is same as in ordinary machine language. Using these interpreters, we can also calculate the values of the elementary functions such as sine, cosine etc. We have also the programs by which we can read and write the numbers with I, F or E type in MACRO/2(or MACRO/3).
