calculator

问题 I'm having issues where my multiplication method is only handling one row, it's currently not advancing to the next row. The add function is working properly, and I'm able to update the current hex number, but for some reason I can only get one line of multiplication to work. Example input: 111# * 333# = 333 123# * 123# = 369 Here is the code in question: LList* Calculator::multiply(LList& left, LList& right) { int product, carry = 0, lval = 0, rval = 0, zeros = 0; bool calculating = true;

问题 I'm trying to multiply the quantity and the price for each item for calculating the total, but I'm getting an error in my alert. $.each(data.items, function(index, d){ var calcultest = d.price * d.qty; alert(calcultest) }); 回答1: Use parseFloat to convert string to Float $.each(data.items, function(index, d){ var Price = d.price.replace(",","."); var calcultest = parseFloat(Price) * parseFloat(d.qty); alert(calcultest.toString().replace(".",",")); }); FIDDLE 回答2: Can you try this, $.each(data

问题 I just made a simple calculator application with AngularJS. What does this program can do: Catch error input when I press . 2 times per series of numbers. Only accept 10 numbers per series of numbers. Check if not complete operate. User only can do 1 formula per 1 series of numbers. But there are still some bugs: When max 10 numbers, if you press delete, the program still accepts more than 10 numbers? Some time after calculation, the program allows to input max 12 numbers? var mainApp =

问题 I'm trying to understand a topic in class about using stacks and queues as a means of programming a calculator. I understand what infix and postfix expression is but how does it make it easier for a program to evaluate an expression and why are queues and stacks ideal in this situation? Thanks 回答1: It makes the order of operations simpler to handle, for example: + * - 4 2 5 3 Can only mean ((4 - 2) * 5) + 3 Which might be more readable for us, but we need to know the order of operations and
