Solution 34653: Performing String Operations on the TI-83 Plus and TI-84 Plus Family of Graphing Calculators.
How do I perform string operations on the TI-83 Plus and TI-84 Plus family of graphing calculators?
The main
function of strings is to display text. In programming, strings allow
programs to display information or prompt the user to perform some
action. Following are some of the operations that can be performed with
strings:
1. Concatenation.
Concatenation means
putting strings one after another and making them one string. For
example, if string1 is "abc" and string2 is "def", then string1+string2
is a new string "abcdef".
To concatenate two or more strings, follow the steps below:
• Enter string1, which can be a string or string name
• Press the [+] key
• Enter string2, which can be a string or string name. If necessary, press the [+] key and enter string3, and so on.
string1+string2+string3...
• Press [ENTER]
2. Converting an equation to a string.
The
Equ>String( command, located in the CATALOG menu, converts the
content of a Y= variable to a string and stores it as a string variable.
3. Converting a string into an equation.
The String>Equ( command, located in the CATALOG menu, convert a string into a variable and stores it in the Y= variable.
4. Converting a string into an expression.
The expr( command, located in the CATALOG menu, converts a string to an expression and executes it.
Please see the TI-83 Plus and TI-84 Plus Family guidebooks for additional information.
