Description
Decimal decimal places can be exactly expressed. For example, 0.75 in octal equals 0.963125 in decimal format (7/8 + 5/64 ). All

Conversion of various basic types in python, binary, octal, decimal, and hexadecimal
All types in python exist as objects.
In python, there is no char type and only a string type. This may be inconvenient to convert the char type to an integer type, but python already provides these built-in functions for conversion.
In python, except integer types, other hexadecimal types can only be represented by stri

After dividing the decimal number by 2, you can enter all the remainder into two parts to obtain the required binary data.

One or two binary number converted to decimal number The basic practice of converting a binary number to a decimal number is to first write the binary number as the weighted coefficient expansion, and then sum it by the decimal addition rule. This practice is known as the "weighted addition" method. Function to convert binary to decimalint binary_decimal (int num
In Python, different hexadecimal conversion (binary, octal, decimal, and hexadecimal) and python hexadecimal
In my opinion, hexadecimal conversion is indeed a common problem. Therefore, in Python, the following code is also indispensable.

In C ++, is 0 decimal or octal? Even in any number of input systems, 0 has only one value, that is, "zero". The reason for asking this question is purely idle. He recently discussed the topic about data with his friends. He said that eight-digit data has almost never been used. I cannot refute it for a moment. Indeed, apart from the commonly used decimal system,
In my impression, it is a common problem to convert into one another, so in Python, the following code should be accepted as util.
