float a = 1+1; costs 17 bytecode.

[revalo]

int bc_base = Clock.getBytecodeNum();
float a = 1 + 1;
System.out.println("Bytecode Cost: " + (Clock.getBytecodeNum() - bc_base));

This prints out 17, which I feel shouldn't be the case for an addition.

(It was actually 2, and the printing/calculating bytecode part used 15 alone)

[kazimuth]

float z = 1 + 1;

generates:

 L0
    LINENUMBER 8 L0
    FCONST_2
    FSTORE 1
    LDC 2
    INVOKESTATIC battlecode/instrumenter/inject/RobotMonitor.incrementBytecodes (I)V

Which is what would be expected.

int bc_base = Clock.getBytecodeNum();
float a = 1 + 1;
System.out.println("Bytecode Cost: " + (Clock.getBytecodeNum() - bc_base));

I still want to look into unexpected bytecode costs, so I'll keep this open.
