Chapter 2 pt. 2

Moving forward in chapter 2.

The chapter goes into Data types and numeric operators, as well as numeric literals and shorthand operators.

From what i have read from the web unlike java there are two different numeric data types in Ruby, Integer and Float.

The remainder operator works differently in Ruby as well.
the statement -7%5 = 2 and not -1 like in Java.
7%-5 will however return -2
In Ruby the statement returns the same sign as the second operand.

Shorthand operators are very similar as well with a few differences.

It is important to note that you cant increment variables like in Java.
For example i++ or j-- etc.

You have to use += or -=

Here is a list of Ruby shorthand operators:

x = 1              this is basically a literal that assigns a variable of 1 to x

x += x             this increments by one (because x is one)

x -= x             this decrements by one  (because x is one)

x += anynumber     this increments by whatever number  

x *= x             this multiplies by x    

x **= x            raises to the power of

x /= x             divides by
