Delphi among the main Greek sanctuaries. Delphi ( / ˈdɛlfaɪ, ˈdɛlfi /; [1] Greek: Δελφοί [ðelˈfi] ), [a] in legend previously called Pytho (Πυθώ), was an ancient sacred precinct and the seat of Pythia, the major oracle who was consulted about important decisions throughout the ancient classical world. The ancient Greeks ...
The signum function is the derivative of the absolute value function, up to (but not including) the indeterminacy at zero. More formally, in integration theory it is a weak derivative, and in convex function theory the subdifferential of the absolute value at 0 is the interval [,], "filling in" the sign function (the subdifferential of the absolute value is not single-valued at 0).
The oracle at Delphi gave oracles from Apollo. Apollo in an oracular function is associated with both plague, purification and truth. Even though the prophecies given by him were ambiguous, he is said to have never uttered a lie. Apollo's oracle at Delphi is the most famous and was the most important oracular site of ancient Greece.

She specifically served as its oracle and was known as the Oracle of Delphi. Her title was also historically glossed in English as the Pythoness.
Sign extension (sometimes abbreviated as sext, particularly in mnemonics) is the operation, in computer arithmetic, of increasing the number of bits of a binary number while preserving the number's sign (positive/negative) and value. This is done by appending digits to the most significant side of the number, following a procedure dependent on ...
Fiat–Shamir heuristic. In cryptography, the Fiat–Shamir heuristic is a technique for taking an interactive proof of knowledge and creating a digital signature based on it. This way, some fact (for example, knowledge of a certain secret number) can be publicly proven without revealing underlying information. The technique is due to Amos Fiat ...

In mathematics, the floor function (or greatest integer function) is the function that takes as input a real number x, and gives as output the greatest integer less than or equal to x, denoted ⌊x⌋ or floor (x). Similarly, the ceiling function maps x to the smallest integer greater than or equal to x, denoted ⌈x⌉ or ceil (x).
