 ### Basic Types
 #### Numbers
+
+Numbers are represented internally as double precision floating point numbers.
+The syntax is very similar to lanugages like C, C++, Java, and Javascript.
+Here are some examples for defining numbers:
+    # Integer representations
+    4
+    -4
+
+    # Floating point representations
+    0.4
+    -0.4
+
+    # Floating point representations with exponents
+    4.0e3
+    4.0e-3
+    -4.0e3
+    -4.0e-3
