Abstract Confusions

Complexity is not a cause of confusion. It is a result of it.

Oracle: On Functions Returning Two or Multiple Values

Mathematically, a deterministic function always returns same value no matter how many times you call. An exception is random function. Any function which involves a random functions will return different values at different times. Here, we are going to discuss about a deterministic Oracle function returning multiple values. To put it simple, In Oracle, can a function have two OUT parameters? In short, yes.

In Oracle, we always know that a function can and should return a value. Is it possible to send two return values?

One Way Only…

This time around, some thing interesting from the world of mathematics.

All of us dealt with functions of different types. We are introduced to functions when very early in school. Single varriable, multi varriable, simple and complex functions. And in college, functions declared, defined and studied. In this post, one such function, known as “one way function” is used widely in computer science.

Wonderful functions from math

Mathematics is full of functions. These functions are applied far and wide else where. Few are used many times where as few others are used little. And very often functions and equations are interchanged. The most celebrated of them all is –

$E=M \times C^2$
