 ### Prefer `double` to `float`, But Test First
 
 Depending on the situation and the compiler's ability to optimize, one may be faster over the other. Choosing `float` will result in lower precision and may be slower due to conversions. On vectorizable operations `float` may be faster if you are able to sacrifice precision.
