Macaulay brackets

Notation used to describe discontinuous functions

Macaulay brackets are a notation used to describe the ramp function { x } = { 0 , x < 0 x , x ≥ 0. {\displaystyle \{x\}={\begin{cases}0,&x<0\\x,&x\geq 0.\end{cases}}} A popular alternative transcription uses angle brackets, viz. ⟨ x ⟩ {\displaystyle \langle x\rangle } . Another commonly used notation is x {\displaystyle x} + or ( x ) {\displaystyle (x)} + for the positive part of x {\displaystyle x} , which avoids conflicts with { . . . } {\displaystyle \{...\}} for set notation.
