Comments are welcome, but please load any comments in the comments section at the bottom of the page. Please include your wiki MONIKER in your comment with the same courtesy that I will give you. Its very hard to reply intelligibly without some background of the correspondent. Thanks,[gold] ---- <> [gold] Here is some eTCL starter code for Aryabhat Sum of Squares and Cubes. ---- ***Testcases Section*** In planning any software, it is advisable to gather a number of testcases to check the results of the program. The math for the testcases can be checked by pasting statements in the TCL console. Aside from the TCL calculator display, when one presses the report button on the calculator, one will have console show access to the capacity functions (subroutines). **** Testcase 1 **** %|table 1|printed in| tcl wiki format|% &| quantity| value| comment, if any|& &| 1:|testcase_number | |& &| 10.0 :|number n| |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 385.0 :|sum of squares series | |& &| 3025.0 :|sum of cubes series | |& %|table 2|printed in| tcl wiki format|% &| quantity| value| comment, if any|& &| 2:|testcase_number | |& &| 3.0 :|number n| |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 14.0 :|sum of squares series | |& &| 36.0 :|sum of cubes series | |& (tclprograms) 1 % **** Testcase 2 **** %|table 2|printed in| tcl wiki format|% &| quantity| value| comment, if any|& &| 2:|testcase_number | |& &| 3.0 :|number n| |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 14.0 :|sum of squares series | |& &| 36.0 :|sum of cubes series | |& **** Testcase 3 **** %|table 3|printed in| tcl wiki format|% &| quantity| value| comment, if any|& &| 3:|testcase_number | |& &| 5.0 :|number n| |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 1.0 :|optional | |& &| 55.0 :|sum of squares series | |& &| 225.0 :|sum of cubes series | |& ---- ***Screenshots Section*** ****figure 1.**** [Capsule Surface Area & Volume and eTCL demo example screenshot] ---- ***References:*** * [Oneliner's Pie in the Sky] * [One Liners] * [A little slide-rule] * [What if you do not have exp()?] * [Category Algorithm] ---- **Appendix Code** ***appendix TCL programs and scripts *** ====== # pretty print from autoindent and ased editor # Aryabhat Sum of Squares and Cubes Series # written on Windows XP on eTCL # working under TCL version 8.5.6 and eTCL 1.0.1 # gold on TCL WIKI, 15jan2017 package require Tk package require math::numtheory namespace path {::tcl::mathop ::tcl::mathfunc math::numtheory } set tcl_precision 17 frame .frame -relief flat -bg aquamarine4 pack .frame -side top -fill y -anchor center set names {{} {number $n :} } lappend names {optional :} lappend names {optional: } lappend names {optional: } lappend names {optional:} lappend names {optional: } lappend names {sum of squares : } lappend names {sum of cubes :} foreach i {1 2 3 4 5 6 7 8} { label .frame.label$i -text [lindex $names $i] -anchor e entry .frame.entry$i -width 35 -textvariable side$i grid .frame.label$i .frame.entry$i -sticky ew -pady 2 -padx 1 } proc about {} { set msg "Calculator for Aryabhat Sum of Squares and Cubes Series from TCL WIKI, written on eTCL " tk_messageBox -title "About" -message $msg } proc calculate { } { global answer2 global side1 side2 side3 side4 side5 global side6 side7 side8 global testcase_number incr testcase_number set side1 [* $side1 1. ] set side2 [* $side2 1. ] set side3 [* $side3 1. ] set side4 [* $side4 1. ] set side5 [* $side5 1. ] set side6 [* $side6 1. ] set side7 [* $side7 1. ] set side8 [* $side8 1. ] set n $side1 set sum_squares [* [* [/ 1. 6. ] $n ] [+ $n 1. ] [+ [* 2. $n ] 1. ]] #set sum_s [/ [* $n [+ $n 1.] ] 2. ] set sum_cubes [+ [/ [** $n 4. ] 4.] [/ [** $n 3. ] 2.] [/ [** $n 2. ] 4.]] set side7 $sum_squares set side8 $sum_cubes } proc fillup {aa bb cc dd ee ff gg hh} { .frame.entry1 insert 0 "$aa" .frame.entry2 insert 0 "$bb" .frame.entry3 insert 0 "$cc" .frame.entry4 insert 0 "$dd" .frame.entry5 insert 0 "$ee" .frame.entry6 insert 0 "$ff" .frame.entry7 insert 0 "$gg" .frame.entry8 insert 0 "$hh" } proc clearx {} { foreach i {1 2 3 4 5 6 7 8 } { .frame.entry$i delete 0 end } } proc reportx {} { global side1 side2 side3 side4 side5 global side6 side7 side8 global testcase_number console show;

"Aryabhat Sum of Squares and Cubes Series Calculator" ====== ---- *** Pushbutton Operation*** For the push buttons, the recommended procedure is push testcase and fill frame, change first three entries etc, push solve, and then push report. Report allows copy and paste from console. For testcases in a computer session, the eTCL calculator increments a new testcase number internally, eg. TC(1), TC(2) , TC(3) , TC(N). The testcase number is internal to the calculator and will not be printed until the report button is pushed for the current result numbers. The current result numbers will be cleared on the next solve button. The command { calculate; reportx } or { calculate ; reportx; clearx } can be added or changed to report automatically. Another wrinkle would be to print out the current text, delimiters, and numbers in a TCL wiki style table as ====== puts " %| testcase $testcase_number | value| units |comment |%" puts " &| volume| $volume| cubic meters |based on length $side1 and width $side2 |&" ====== ---- [gold] This page is copyrighted under the TCL/TK license terms, [http://tcl.tk/software/tcltk/license.html%|%this license]. **Comments Section** <> Please place any comments here, Thanks. <> Numerical Analysis | Toys | Calculator | Mathematics| Example| Toys and Games | Games | Application | GUI
