prec

precision_t

This handles whether to use double or single float precision. By default, precision_t is set to double. One can edit the line #define PRECISION double to #define PRECISION float to change it to float.

Data

Data is a union that stores some 1d array of data depending on the dtype. Use Data.int_data to store int values. Data.prec_data, Data.string_data for precision_t, string respectively. This helps in making more complex types like Vectors, helping us to store different datatypes under the same type "Vector".

DataType

This helps us to label the dtypes. INT, PREC, STRING corresponds to int, precision_t, string type respectively.

arith_oper

This helps us to label various arithmetic operations like add, subtract, multiply, divide and power as ADD, SUB, MUL, DIV, POW
