simplest way to replicate scientific notation conversion:

`$mu(floor, df(S))$`

→ outputs something like `1.6259072E9`

example problem with the output:

`$df(S)$`

→ outputs unix time, as expected

`$mu(floor, df(S) / 20) * 20$ `

→ expected unix time rounded down to the nearest 20 seconds, outputs a number off by way more (probably due to rounding)

as a workaround, it's possible to replace `df(S)`

with

`tc(cut, df(S), -6)`

which uses the last 6 digits of `df(S)`

, at the cost of possible jump problems every ~2 years.

additionally, you cannot write number literals in scientific notation, as they will get interpreted as text:

`$1.9E9 / 10$`

→ interpreted as text, returns `1.9E9/10`
