Operators and symbols

Infix operators

This list contains all the infix operators, an example of how the operator would be used, a short explanation, and its precedence. An operator with a higher precedence will be grouped before an operator with less precedence.

Comparison order

All six comparison operators work between any two values and use the same total order as sorted. Different types are ordered as follows:

Bool < Char < Number < Symbol < String < Tuple < List < Set < Dictionary < Function < Range < Generator < Error.

Integers, floats, and fractions share numeric ordering. Comparisons use the exact stored value, without rounding integers or fractions to floats. Thus 1 = 1.0, but 1//10 < 0.1 because the float is slightly greater than one tenth. Positive and negative zero compare equal. Infinities bound finite numbers; negative NaNs sort before negative infinity and positive NaNs after positive infinity, with NaN bit patterns providing a deterministic order within each group.

Collections compare lexicographically, recursively using this order. Sets compare their sorted elements; dictionaries compare their sorted key/value pairs. Equal numeric values are also interchangeable as set elements and dictionary keys. Function and generator ordering can depend on identity within an execution; comparing a generator does not consume it.

For example, 0.5 < "cesar" and [0.5] < [1] are both true.

Prefix operators

This list contains all the prefix operators, an example of how the operator would be used, and a short explanation.
