LaTex How to remove trailing zeros in scientific notion

Question

When using large numbers I'd like to use scinetific notation in LaTex. However, because of the trailing zeros it gets worse. E.g.


um[scientific-notation=true,  exponent-product=\ensuremath{\cdot}]{250000000000000000000}

If these figures aren't significant, you could input it as


um[scientific-notation=true,  exponent-product=\ensuremath{\cdot}]{25e19}
