It’s the fractional part, that mean {x}=x−⌊x⌋. For example, if x=3.456, then {x}=x−⌊x⌋=3.456−3=0.456. Notice that {x}∈[0,1) for all x∈R. https://math.stackexchange.com/questions/1821405/what-do-curly-brackets-mean-in-this-number-theory-equation/1821406#1821406.

Lesson Summary. Parentheses, brackets, and braces are ways of separating parts of a mathematical expression from one another, and they all look quite similar. Parentheses are smooth and curved ( ), brackets are square [ ], and braces are curly { }. In mathematics, they are mostly used for order of operations.

Curly brackets are used to show where a function starts and ends. Simple.
