Calculation method of hexadecimal mathematics

Main article: Base conversion

Decimal to Hex

Take the remainder theorem, for example, convert 4877 ₁₀ to hexadecimal:

4877 ÷ 16 = 304 .... 13 (D)

304 ÷ 16 = 19 .... 0

19 ÷ 16 = 1 .... 3

1 ÷ 16 = 0 .... 1

This counts to 4877 ₁₀ = 130D ₁₆

Functions in Hex Programming

Visual Basic

• Hexadecimal to Decimal: Decimal (Long) = CLng ("& H" & Hex (String))

• Decimal to Hexadecimal: Hexadecimal (String) = Hex $ (Decimal)

Javascript

Javascript can use the toString () function to convert decimal digits to other arbitrary decimal formats (String type)

Python

Call Python's built-in int () function to convert the string into a number. ^[2]
