dreturn

Return double from method

Bytecode

Type Description
u1 dreturn opcode = 0xAF (175)

Stack ..., value.word1, value.word2 => [empty]

Description
dreturn pops the two-word double off the stack and pushes it onto the operand stack of the invoker (i.e. the method which used invokevirtual, invokespecial, invokestatic or invokeinterface to call the currently executing method). All other items on the current method's operand stack are discarded. If the current method is marked as synchronized, then an implicit monitorexit instruction is executed. Then the current method's frame is discarded, the invoker's frame is reinstated, and control returns to the invoker. This instruction can only be used in methods whose return type is double.

The returning method must have return type double. The value must be of type double. The value is popped from the operand stack of the current frame and pushed onto the operand stack of the frame of the invoker. Any other values on the operand stack of the current method are discarded. If the returning method is a synchronized method, the monitor acquired or reentered on invocation of the method is released or exited (respectively) as if by execution of a monitorexit instruction.

The interpreter then returns control to the invoker of the method, reinstating the frame of the invoker.
