Latex number formatting

from physipy import units, m
W = units["W"]

x = 61685027506808.49 * W/m**2
print(x.value)          # 61685027506808.49
print(x)                # 61685027506808.49 kg/s**3
print(x._repr_latex_()) # $61700000000000.0\,\frac{kg}{s^{3}}$
x # in notebook this shows the rendered latex, using 61700000000000 as base value

The latex number formatting applies some rounding that doesn't seem smart
