incorrect operator predudece

[Roger-luo]

e.g the following

s = """OPENQASM 2.0;
gate test_gate2(theta, phi) qreg_2, qreg_3, qreg_1 {
  x qreg_1;
  z qreg_2;
  rx(-(sin(theta))+2.0) qreg_3;
  rx(sin(theta)+tan(phi)) qreg_3;
  ry(cos(phi)-ln(phi)) qreg_3;
  ry(cos(phi)*sqrt(phi)) qreg_3;
  CX qreg_1, qreg_3;
}
"""
target_qasm = OpenQASM.parse(s).prog[1]

julia> target_qasm.body[3].cargs[1]|>OpenQASM.print_qasm
-sin(theta)+2.0

the negative sign is outside of sin(theta)+2.0 instead of (-sin(theta)) + 2.0

@thautwarm know how to fix this?

Hi @Roger-luo,

I don't see any differences between -( sin(theta) )+2.0 and (-sin(theta)) + 2.0. I think that the ( ) will do nothing because there is only a single value inside. For example. (a) + (b) will only become a + b.

But maybe you could elaborate more about the bug?

I don't quite remember what was the issue, maybe I thought the sign was -(... + 2.0) I'm gonna close this first.
