Input [promptString,] var Input [promptString], var pauses the program, displays promptString on the Program I/O screen, waits for you to enter an expression, and stores the expression in variable var. If you omit promptString, "?" is displayed as a prompt. Program segment: © :For i,1,9,1 : "Enter x" & string(i)! str1 : Input str1,#(right(str1,2)) :EndFor © InputStr CATALOG InputStr [promptString,] var Pauses the program, displays promptString on the Program I/O screen, waits for you to enter a response, and stores your response as a string in variable var. If you omit promptString, "?" is displayed as a prompt. Note: The difference between Input and InputStr is that InputStr always stores the result as a string so that " " are not required. Program segment: © :InputStr "Enter Your Name",str1 © inString( ) MATH/String menu inString(srcString, subString[, start]) ⇒ integer Returns the character position in string srcString at which the first occurrence of string subString begins. start, if included, specifies the character position within srcString where the search begins. Default = 1 (the first character of srcString). inString("Hello there","the") ¸ 7 "ABCEFG"! s1:If inString(s1, "D")=0:Disp "D not found." ¸ D not found. If srcString does not contain subString or start is > the length of srcString, returns zero. int( ) CATALOG int(expression) ⇒ integer int(list1) ⇒ list int(matrix1) ⇒ matrix Returns the greatest integer that is less than or equal to the argument. This function is identical to floor(). int(ë 2.5) ¸ ë 3. int([-1.234,0,0.37]) ¸ [-2. 0 0.] The argument can be a real or a complex number. For a list or matrix, returns the greatest integer of each of the elements. intDiv() CATALOG intDiv(number1, number2) ⇒ integer intDiv(list1, list2) ⇒ list intDiv(matrix1, matrix2) ⇒ matrix Returns the signed integer part of argument 1 divided by argument 2. For lists and matrices returns the signed integer part of argument 1 divided by argument 2 for each element pair. intDiv(ë 7,2) ¸ ë3 intDiv(4,5) ¸ 0 intDiv({12,ë 14,ë 16},{5,4,ë 3}) ¸ {2 ë 3 5} integrate See ‰(), page 907. 830 Appendix A: Functions and Instructions
