Has anyone ever seen this? Where? Thanks!

I haven't seen the notation as you used it, to give the minimum of two numbers, but I have seen this:

[tex]\lceil x \rceil ^k[/tex]

to mean min(x,k).

Has anyone ever seen this? Where? Thanks!

##\lceil x \rceil##, also called the smallest integer function. It is defined as being the smallest integer that is greater than or equal to x. Many programming languages, including C, C++, and others, have a ceiling function,

For example, ##\lceil 1.8 \rceil = 2##.

The counterpart is the floor function, or greatest integer function, denoted ##\lfloor x \rfloor##. C, C++, and others have

For example, ##\lfloor 2.35 \rfloor = 2##.

I agree with micromass that ##\lceil x \rceil^k## is terrible notation.
