fmt = fmt_statistic rounding with false sign

[ktheile]

When I have a coefficient of -0.000000011*, and set the fmt statistic to less than 8 digits, the rounded value becomes 0.000, so with a positive sign. This should be rounded with at least a negative sign, indicating the narrowly negative direction

fmt = fmt_statistic(estimate = 9,std.error=4,p.value=3, statistic = 2)
