Summary

Often the usefulness of a language system is dependent on its function libraries and operator built-ins. This is especially true in scientific systems such as FORTRAN. Operator built-ins usually support integers, booleans, reals, double-precision 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
QuoteRef: sammJE_1969 ;;99 rational arithmetic eg 1/3 + 1/3 = 2/3
QuoteRef: sammJE_1969 ;;242 lots of math computations eg least squares, differentiation, plotting
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]

Quote: builtin subroutines (e.g., sin and sqrt) represented by F^2 and F^1; the Flexowriter had true superscripts
