Convert short to byte
Format
s2b
Forms
s2b = 91 (0x5b)
Stack
…, value → …, result
Description
The value on top of the operand stack must be of type short. It is popped from the top of the operand stack, truncated to a byte result, then sign-extended to a short result. The result is pushed onto the operand stack.
Notes
The s2b instruction performs a narrowing primitive conversion. It may lose information about the overall magnitude of value. The result may also not have the same sign as value.
