A subset of important internal Maple data types
| Type | Explanation |
|---|---|
| SUM | Sums. Internally stored with factors for each summand, i.e., “x+y” would be stored as “x·1+y·1” |
| PROD | Products |
| EXPSEQ | Expression sequence is a kind of list. The arguments of functions are stored in such sequences |
| INTPOS | Positive integers |
| INTNEG | Negative integers |
| COMPLEX | Complex numbers with real and imaginary part |
| FLOAT | Float numbers are stored in the scientific notation with integer values for the exponent n and the significant m in m·10n |
| RATIONAL | Rational numbers are fractions stored in integer values for the numerator and positive integers for the denominator |
| POWER | Exponentiation with expressions as base and exponent |
| FUNCTION | Function invocation with the name, arguments and attributes of the function |
