Description
The value1 must be of type long and value2 must be of type int. The values are popped from the operand stack. A long result is calculated by shifting value1 left by s bit positions, where s is the low six bits of value2. The result is pushed onto the operand stack.
Notes
This is equivalent (even if overflow occurs) to multiplication by 2 to the power s. The shift distance actually used is therefore always in the range 0 to 63, inclusive, as if value2 were subjected to a bitwise logical AND with the mask value 0x3f.
