Conversions in Ruby

While working with exploits and modules, we will require tons of conversion operations. Let us see some of the conversions we will use in the upcoming sections:

• Hexadecimal to decimal conversion:

It's quite easy to convert a value to decimal from hexadecimal in Ruby using the inbuilt hex function. Let's look at an example:

       irb(main):021:0> a= "10"
       => "10"
       irb(main):022:0> a.hex
       => 16

We can see we got the value 16 for a hexadecimal value 10.

• Decimal to hexadecimal conversion:

The opposite of the preceding function can be performed with to_s function as follows:

       irb(main):028:0> 16.to_s(16)
       => "10"
