+### Semantic Byte Casting
 
-:::caution
-When casting bytes types to integer, you should be sure that the bytes value fits inside a 64-bit signed integer, or the script will fail.
-:::
+Bytes to bytes casting is just semantic and can be helpful for working with `LockingBytecode` global functions which expect a specific length input. To utilize byte-padding, convert to `int` and utilize the integer padding.
+
+#### Example
+```solidity
+bytes pkh = nftcommitment.split(20)[0];
+bytes25 lockingBytecode = new LockingBytecodeP2PKH(bytes20(pkh)):
+```
 
 ## Operators
 An overview of all supported operators and their precedence is included below. Notable is a lack of exponentiation, since these operations are not supported by the underlying Bitcoin Script.
