+#### Token quantity
+
+You can easily manage quantities as special, `bigint` based floating point numbers that keep precision, using the `token.Quantity` field. This field provides a [`Quantity`](#quantities) instance every time it's called, with a pre-configured denomination matching the token's denomination. Read more about quantities [here](#quantities).
+
+```ts
+// initialise a quantity from a token
+const amountToSend = aoCredToken.Quantity.fromString("752.34");
+```
+
 #### Wallet balance
 
 You can query the token balance for an address. This will return a `Quantity` instance.
