Meaning of numbers in “col-md-4”,“ col-xs-1”, “col-lg-2” in Bootstrap
... of columns always add up to 12. It can be less than twelve, but beware if more than 12, as your offending divs will bump down to the next row (not .row, which is another story altogether).

Selecting only numeric columns from a data frame
...ly, even though it's less code
## nums <- sapply(x, is.numeric)
For a more idiomatic modern R I'd now recommend
x[ , purrr::map_lgl(x, is.numeric)]

Moving decimal places over in a double

@Peter Lawrey: Can you explain more why whether the number is odd or even would affect rounding? I'd think that /=100 and *=.01 would be the same because even though 100 is an int, it will be converted into 100.0 anyways as a result of type coercion.
