**Sumerian Workday Time & Account Calculator with demo examples eTCL numerical analysis** This page is under development. 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 *** Ratios and metal prices *** In the eTCL calculator, kilograms are used with the price ratios of copper (1/90) and tin (1/20) for UrIII. From the trial calculations, these price ratios were transferred correctly to kilograms of silver. The price table contains redundant entries from different texts. However, the trade values or price ratios were undoubtedly different in different eras, countries, and texts. *** Pseudocode and Equations *** ====== Sumerian price in silver = [/ liters 300.] Sumerian price in liters grain = [* silver 300.] # 1 silver piece = 1 gur = 300 liters of grain liters = [* volume_in_cubic_cm .001] original copper mass + original tin mass - product mass = smelter loss original metal mass - product mass = smelter loss original metal mass * average refining loss in percent= refining loss original metal mass - refining loss = product mass 30 to 40 kg of charcoal for 1 kg of copper, rule of thumb (for smelting copper in raw ore) original metal mass * price ratio in silver 1/N = price in silver 6 bundles or 60 kgs of reeds for 1/2 mana of copper, rule of thumb 120 manas or 60 kgs of reeds for 1/2 mana of copper, rule of thumb bundle of reeds was 20 manas or 10 kg price? = raw materials + labor + profit price? = raw materials + heat process price? = raw materials + labor average price per unit = revenue / units sold ====== *** Table 1 , UrIII Prices*** %| UrIII Metal prices|per silver shekel etc| country, era|% %| quantity| value| comment, if any|% &| copper | 3 minas= 180 shekels | Babylon, Esnunna Code prices, 1900 BCE, for comparison |& &| copper | 1.5 minas= 90 shekels | NeoSumerian, UrIII, circa 2300 BCE|& &| copper | 80 shekels | NeoSumerian, UrIII, circa 2300 BCE|& &| tin | 12 shekels| NeoSumerian, UrIII, circa 2300 BCE|& &| tin | 20 shekels | NeoSumerian, UrIII, circa 2300 BCE|& &| red gold | 15 shekels | NeoSumerian, UrIII, circa 2300 BCE|& &| gold | 7 shekels | NeoSumerian, UrIII, circa 2300 BCE|& &| gold | 20 shekels | NeoSumerian, UrIII, circa 2300 BCE|& ---- *** Table 2 , OB Prices*** %|O.B.

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 **** ---- **** Testcase 2 **** ---- **** Testcase 3 **** ---- ***Screenshots Section*** ****figure 1.**** [http://s1.postimg.org/7nrwm5lnz/sumerian_bronze_calculator_TCL_WIKI_2.png] ---- ***References:*** * Robert Englund, UCLA [https://cdli.ucla.edu/staff/englund/publications/englund2012a.pdf] * Ur III Tablets in the Valdosta State University, search on cdli * Cuneiform Digital Library Journal, search on Equivalency Values * Ur III Equivalency Values[http://cdli.ox.ac.uk/wiki/doku.php?id=ur_iii_equivalency_values] * Especially, the Ur III Equivalency Values and library texts for workday (u4) keyword. * The Sumerian keywords search on the cdli * are very effective, but major size files to download ---- **Appendix Code** ***appendix TCL programs and scripts *** ====== # pretty print from autoindent and ased editor ====== ---- *** 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.
