科學計算機

Puli_College 為工程師及工程科系學生發展一套計算機，分別為基礎計算機、科學計算機、統計計算機，以及解方程計算機。
本機為科學計算機，包含常用函數，適合科學及工程人員使用。40個按鍵區分為七類，
(1) 函數鍵：三角函數鍵，sin，cos，tan，反三角函數鍵，asin，acos，atan，雙曲函數，cosh，sinh，tanh，及絕對值函數，abs。
(2) 指數及對數函數鍵：自然指對數，ln，exp，10為底指對數，log，10^，常見次方函數，^(1/2)，^2，^(1/3)，^3，任意次方數，^y。
(3) 數字鍵：1 2 3 4 5 6 7 8 9 0，小數點 .，以及圓周率π及自然對數e。
(4) 四則運算建：+ - ╳ / 。
(5) 括號鍵：( )。
(6) 等號鍵：=，按下等號鍵即進行算式運算並顯示結果。
(7) 清除鍵：clear。欲進行下一則運算時，先行按下清除鍵。
40個按鍵並非任何情況下皆有效，例如，右括號數不可多於左括號數，或一串數字中不可出現兩個小數點；於是，任何按鍵均區分為有效及無效兩種情況，有效按鍵顯示為較明亮之按鍵原色，無效按鍵顯示為較暗淡之半透明背景色。 Puli_College for engineers and engineering students to develop a computer department, were based computer, computer science, statistics, computer, computer and solving equations.
    The machine is computer science, including the commonly used functions for scientific and engineering personnel. 40 keys divided into seven categories,
(1) Function keys: trigonometric key, sin, cos, tan, inverse trigonometric functions keys, asin, acos, atan, hyperbolic function, cosh, sinh, tanh, and the absolute value function, abs.
(2) index and logarithmic functions keys: refers to the natural logarithms, ln, exp, 10 refers to the number for the bottom, log, 10 ^, common to the power function, ^ (1/2), ^ 2 ^ (1/3), ^ 3, any perfect power, ^ y.
(3) the number buttons: 1234567890, decimal points, and pi π and the natural logarithm e.
(4) to build four operations: + - ╳ /.
(5) Bracket key :().
(6) equals key: =, namely, press the equals key formula calculates and displays the results.
(7) Clear key: clear. For the next time the operation, first pressing the Clear key.
    40 keys are not valid in any case, such a right can not be more than the number of brackets from the left parenthesis, or a string of numbers can not appear in two decimal points; thus, no keys are divided into valid and invalid both cases, the effective key appears as the brighter colors of the keys, invalid key appears as the translucent background color is dull.
