Is there a macro in latex to write ceil(x) and floor(x) in short form? The long form
\left \lceil{x}\right \rceil
is a bit lengthy to type every time it is used.

Using \DeclarePairedDelimiter from mathtools, you could define macros \ceil and \floor, which will scale the delimiters properly (if starred):
\documentclass{minimal}
\usepackage{mathtools}
\DeclarePairedDelimiter\ceil{\lceil}{\rceil}
\DeclarePairedDelimiter\floor{\lfloor}{\rfloor}
\begin{document}
\begin{equation*}
\floor*{\frac{x}{2}} < \frac{x}{2} < \ceil*{\frac{x}{2}}
\end{equation*}
\end{document}
Result:
Scaling delimiters with
\floorand\ceil
