@Vikram I want the smallest integer strictly greater than $x$.

comment Strict ceiling and floor notation
@Vikram That doesn't work. Consider $x = 0.95$ in $\lceil x + 0.1 \rceil$.

@JordanGlen That notation works great, thanks.

comment Strict ceiling and floor notation
I'd definitely define it for the reader regardless of which notation I used, I was more looking for examples that other people had come up with, so I can pick one that I like. From the answers I'm getting, maybe I didn't make that clear enough.

comment Polynomials vs polynomial functions
And the elements of $R[X]$ are in no way functions, so we can't write $f(x)$ for $f \in R[X]$?

comment Polynomials vs polynomial functions
@GitGud So a polynomial function is determined by the values it takes when evaluated in the domain of the function, whereas a polynomial is determined by it's coefficients?

@ChristianBlatter What would be a less condensed way of writing this? I'm interested to know where the notation comes from.

comment What was the first bit of mathematics that made you realize that math is beautiful? (For children's book)
@Cruncher which is zero. $\lim_{n \to \infty} 10^{-n} = 0$, as does $\lim_{n \to \infty} 10^{-n} b$, which corresponds to any $0.000...b_0...b_n$, where $b_k$ is the kth digit of the decimal expansion of b.
