+          The decimal positions that lead to this currency smallest unit.
+
+          For example: since Japanese Yen (JPY) have no cents, this value is 0.
+
+          On the other hand, since the US Dollar (USD) is composed of cents, and each dollar equals 100 cent, this value is 2.
+
+          To convert from normal unit (Dollar) to smallest unit (Cent), multiply by `10^decimal_positions`.
+          To convert from smallest unit (Cent) to normal unit (Dollar), divide by `10^decimal_positions`.
