bug in subtraction with signed 0 #7

Open tzwaenn opened this issue almost 7 years ago

the addition unit correctly computes -0 + (-0) = -0 but in the subtraction unit, the corresponding case wrongly gets +0: -0 - (+0) = +0 signal values: fpu_op_i 1 opa_i 8000000 opb_i 0000000 rmode_i 0 output_o 00000000, but should be 8000000
