Class L2d

java.lang.Object
  jef.dna.instructions.impl.InstructionAncestor
      jef.dna.instructions.impl.L2d

All Implemented Interfaces:

java.lang.Cloneable, Instruction, BytesCountable

public class L2d
extends InstructionAncestor

This class maps the L2D bytecode instruction which converts a long to a double. The value to be converted is popped from the operand stack, where the resulting double is pushed back.
