ActionAnd
ActionAnd performs a logical AND of two numbers.
| Field | Type | Comment |
|---|
| ActionAnd | ACTIONRECORDHEADER | ActionCode = 0x10 |
ActionAdd does the following:
- Pops value A off the stack.
- Pops value B off the stack.
- Converts A and B to floating-point; non-numeric values evaluate to 0.
- If both numbers are nonzero, true is pushed to the stack for SWF 5 and later (1 is pushed for SWF 4);
otherwise, false is pushed to the stack for SWF 5 and later (0 is pushed for SWF 4).
