Summary
Often the usefulness of a language system is dependent on its function libraries and operator builtins. This is especially true in scientific systems such as FORTRAN. Operator builtins usually support integers, booleans, reals, doubleprecision reals and strings. Some other operations are double precision intermediates, the FOCUS number system, rational arithmetic, multiple precision arithmetic, array operations, set operations, string arithmetic, and integer range predicates.

Quotations
QuoteRef: hehnEC7_1975 ;;12 all kinds of set and list operations, standards plus various mapping operations
 QuoteRef: storEF_1970 ;;27 range (x,y,z) true iff x=<y=<z

 Quote: if a count reaches its limit, reduce by half, increment an overflow count in a hashed table, and set a flag; reverse for decrementing [»lampBW10_1983]
