I believe it is for calculus grouping.  It may be called a sigma

You can use those brackets any way you want to in a text file, but in a program they may have defined values or characteristics.


Long before computer programmers, now called developers came along, it was part of mathimatical symbols.  JorliD beat every one to the punch.

Thank you Chewie. I vaguely remember it from Calculus.  Just don't ask me how bad I did in the class.

{} are curly brackets and denote a quantity or set, for example X={2,4,6,8}

sigma is from the greek alphabet... Σ, σ, or ς

Σ generally used to indicate summation in calculus

σ having several uses including standard deviation of a population in statistics, and as the Stefan-Boltzmann constant from physics
