问题 At the moment, I'm trying to make a calculator using the java programming language. However, I need to know whether or not java uses BODMAS so that I'll know whether to make an algorithm that implements BODMAS or continue making the calculator. Does java use BODMAS? 回答1: It's BODMAS not BOMDAS (division is before multiplication). Yes Java does, there is also precedence rules that it uses about operators not included in BODMAS too A full list can be found in the Java documentation here: http:/

Assembly big numbers calculator

问题 I've been given an assingment to make a calculator in 8086 assembly that will add, substract, multiply and divide big decimal numbers. These numbers can be 30 digits long at most. I've used 3 arrays to house these numbers (num1, num2, result). I'm stuck at the addition, because every time I run the program, it displays that the result array is empty (it shows a plus sign and 60 zeroes) can you tell what is wrong with my code? ADDER: MOV BP, offset num1 MOV SI, offset num2 MOV DI, offset

Drop un-needed decimal “.0”

由 心不动则不痛 提交于 2021-02-02 09:54:25
问题 I'm making a simple calculator and I am having an issue with it showing a decimal on what I want to just be a whole number. For example, if the entered expression is "50 + 50" the answer will come out "100.0". I understand that it's happening because my output is set as a double, but I can't figure out how to convert those numbers to integer only when the answer is ".0". My output answer code: fun equal (view: View) { secondnum = editText.text.toString() decpressed = 0 var sum = 0.0 when (op)
