##
## Here's a comparison of about how long [Dec] takes to perform a given operation compared to [F64],
## based on benchmarks on an [M1](https://en.wikipedia.org/wiki/Apple_M1) CPU:
## * [add] 0.75x
## * [sub] 0.75x
## * [mul] 4x
## * [div] 32x
## * [sin] 3x
## * [asin] 9x
## * [add] 0.6x
## * [sub] 0.6x
## * [mul] 15x
## * [div] 55x
## * [sin] 3.9x
## * [cos] 3.6x
## * [tan] 2.3x
## * [asin] 1.8x
## * [acos] 1.7x
## * [atan] 1.7x
##
## Keep in mind that arithmetic instructions are basically [the fastest thing a CPU does](http://norvig.com/21-days.html#answers),
## so (for example) a network request that takes 10 milliseconds to complete would go on this
