A.3.1 Function Names

The names of built-in functions follow some general guidelines.

  • The name consists of complete English words, or standard mathematical abbreviations. American spelling is used.
  • The first letter of each word is capitalized.
  • Functions whose names end with Q usually "ask a question", and return either True or False.
  • Mathematical functions that are named after people usually have names in Mathematica of the form PersonSymbol.
