I wanna print a number and its uncertainty in the following way:
x = (4.23 ± 0.01) e3
where the value and its uncertainty are two different variables.
mean = 4230
uncertainty = 10
print("x is %.2e \u00B1 %.2e" % (mean, uncertainty))
I want them to be formatted with the same power of the exponential in the scientific notation. what I get is
x is 4.23e+03 ± 1.00e+01
Assuming mean integer, a way to do it might be
>>> mean = 4230
>>> uncertainty = 10
>>> pos_to_first = len(str(mean)) - 1
>>> f"({mean/10**pos_to_first} ± {uncertainty/10**pos_to_first}) E{pos_to_first}"
'(4.23 ± 0.01) E3'
