Def code does not work for negative integers.

[doug2019]

The def code when it results in negative does not work. I don't know how to solve it.

def conversao(x):
    if x < GPa:
        return(str(int(x/MPa))+"MPa")
    elif x >= GPa:
        return(str(int(x/GPa))+"GPa")
GPa=1000000000
MPa=1000000
y=-2*10**9
z=y/2
print(f"{conversao(z)}")

The output should be -1GPa and not -1000MPa.

I would test against the absolute value of x (abs(x)) instead of just x.
