Preface
Have you ever thought about writing a calculator yourself? Enter some mathematical expressions to calculate and parse
I recently re-learned the CPU architecture, used the binary complement principle to eliminate the differences between the number of symbols and the number of unsigned numbers, and integrated the subtraction calculator to the addition calculator,
The built-in calculators in windows are also quite a lot used, but basically they all do some simple addition, subtraction, multiplication, division, and frankly speaking, I didn't even know the difference between Ce and C keys before, let alone
This article mainly introduces the decimal negative conversion to binary, octal, hexadecimal knowledge sharing, the need for friends can refer to the nextProgram apes may not be unfamiliar with binary systems, which are widely used in computing
Program apes may be unfamiliar with binary systems, which are widely used in computing technology. Binary data is a number represented by 0 and 12 digits. But many people will convert binary to integers, but how do you represent negative numbers in
The previous talk briefly introduces constants and variables, which add a little bit to the basics of computer---binary.Let's take a look at how the usual expression of an integer, the most common must be expressed in Arabic numerals, such as "12",
1. Convert decimal to binary
To convert decimal to binary, You need to convert the integer part and the decimal part. The integer is divided by 2, and the quotient is divided by 2. After obtaining 0, you can sort the remainder in reverse order.
