Python - Mathematical Functions - Hexadecimal, Binary, Exponential, Absolute, Round

🐍 Some mathematical functions are in-built in python. Here are some of them. Convert Decimal to Hexadecimal hex(246) Output: '0xf6' hex(512) Output: '0x200' 0x is prefix to all hexadecimal numbers in output. The number after 0x is the hexadecimal value. Convert Decimal to Binary bin(1234) Output: '0b10011010010' bin(246) Output: '0b11110110' bin(512) Output: '0b1000000000' Exponential Function pow() function is similar to num1**num2, but it comes useful when you want to execute (num1**num2)%num3. Passing three arguments to pow(), does this. pow(3,4) Output: 81 This works just like 3**4 pow(3,4,5) Output: 1 But this, works equivalent to (3**4)%5. Either of the two ways can be used. At this point I feel (3**4)%5 is better, as anybody reading the code will understand what is being done immediately. While with pow(2,3,4), the person may have to refer to documentation to understand how this function works. Absolute Value The function abs() is used ...
