Калькулятор
Это простой калькулятор. Его код: <SCRIPT language="JavaScript">
<!--
var memory1 = 0
var control = 0
var InOperator = ""
var FirstRound = 1
function Digit(number) {
var string_mem = "";
if (control == 1){
document.Calculator.Output.value = number;
control = 0;
}
else{
string_mem = document.Calculator.Output.value;
string_mem = string_mem + number;
document.Calculator.Output.value = string_mem;
}
}
function ClearAll(){
document.Calculator.Output.value = "";
memory1 = 0;
FirstRound = 1;
}
function Calculate(Operator){
var memory2 = 0;
memory2 = parseFloat(document.Calculator.Output.value);
control = 1;
if (FirstRound == 1){
memory1 = parseFloat(document.Calculator.Output.value);
FirstRound = 0;
}
else{
if (InOperator == "+")
memory1 = (memory1 + memory2);
if (InOperator == "-")
memory1 = (memory1 - memory2);
if (InOperator == "*")
memory1 = (memory1 * memory2);
if (InOperator == "/")
memory1 = (memory1 / memory2);
}
InOperator = Operator;
document.Calculator.Output.value = memory1;
}
function SumUp(){
memory2 = parseFloat(document.Calculator.Output.value);
control = 1;
if (InOperator == "+"){
memory1 = (memory1 + memory2);
}
else if (InOperator == "-"){
memory1 = (memory1 - memory2);
}
else if (InOperator == "*"){
memory1 = (memory1 * memory2);
}
else if (InOperator == "/"){
memory1 = (memory1 / memory2);
}
InOperator = "";
document.Calculator.Output.value = memory1;
