Utility Functions 26 Figure 26-0
Table 26-0
This chapter provides a listing of a number of utility functions documented in the
“Utility Functions Reference” in the Newton Programmer’s Reference. The
following groups of functions are included:
■ Object system
■ String
■ Bitwise
■ Array and sorted array
■ Integer Math
■ Floating point math
■ Control of floating point math
■ Financial
■ Exception handling
■ Message sending and deferred message sending
■ Data extraction
■ Data stuffing
■ Getting and Setting Global Variables
■ Miscellaneous
Four of the functions described in the Object system section are designed to clone,
or copy, objects. These functions each behave slightly differently. Table 26-1
summarizes their actions. The “Recurs” column indicates if references within the
object are copied. The “Follows magic pointers” column indicates if objects
referenced through magic pointers are copied. The “Ensures object is internal”
column indicates if the function ensures that all parts of the object exist in internal
RAM or ROM. The “Copies object” column indicates if the object is copied.
