TI-BASIC is strongly and mostly statically typed. Most variables, besides lists and programs, have predefined names and allowed types. Each variable can usually only hold one data type, the exceptions are the numeric and all list variables which can hold either real or complex values.
Values may range from 1E-99 to 1E99 with 14 digits of accuracy, [5] although only 10 digits are usually displayed to users. The limit of 27 variables, however, may be expanded through the use of lists, matrices, and manipulation of integer notation. A list or matrix can be used to contain unique real variables which can be individually referenced.
dc: "Desktop Calculator" arbitrary-precision RPN calculator that comes standard on most Unix-like systems. KCalc, Linux based scientific calculator; Maxima: a computer algebra system which bignum integers are directly inherited from its implementation language Common Lisp. In addition, it supports arbitrary-precision floating-point numbers ...
Rather than storing values as a fixed number of bits related to the size of the processor register, these implementations typically use variable-length arrays of digits. Arbitrary precision is used in applications where the speed of arithmetic is not a limiting factor, or where precise results with very large numbers are required.
Python supports a wide variety of string operations. Strings in Python are immutable, so a string operation such as a substitution of characters, that in other programming languages might alter the string in place, returns a new string in Python. Performance considerations sometimes push for using special techniques in programs that modify ...
In computer programming, bounds checking is any method of detecting whether a variable is within some bounds before it is used. It is usually used to ensure that a number fits into a given type (range checking), or that a variable being used as an array index is within the bounds of the array (index checking).
Variable-length arithmetic operations are considerably slower than fixed-length format floating-point instructions. When high performance is not a requirement, but high precision is, variable length arithmetic can prove useful, though the actual accuracy of the result may not be known.
Analogous to the way an ASCII or EBCDIC character string representing a decimal number is converted to a numeric quantity for computing, a variable-length string can be converted as x k−1 a k−1 + x k−2 a k−2 + ⋯ + x 1 a + x 0.
