absoluteY

AbsoluteY is a term used in mathematics and computer science to denote a non-negative quantity associated with the vertical dimension. In its most general form, absoluteY refers to the absolute value of a y-related quantity, typically written as |y| or abs(y). When applied to a point (x, y) in the plane, absoluteY can denote the magnitude of the vertical component, disregarding direction.

In programming and graphics, absoluteY is often used as a variable name representing either the absolute vertical distance between two positions (for example, abs(y2 - y1)) or the y-coordinate of a point expressed in an absolute or global coordinate system rather than a local one. The concept is useful wherever vertical magnitude is needed without regard to sign, such as collision checks, layout calculations, or visual effects that depend on vertical displacement rather than direction.

Examples illustrate the idea: a point (4, -9) has absoluteY equal to 9. If two points have a vertical difference Δy = -12, then absoluteY is 12. In contrast to the signed y coordinate, absoluteY provides a non-negative measure of vertical extent.

Relation to other concepts includes the absolute value function, vector magnitude in two dimensions, and vertical displacement. While the term appears across domains, its exact interpretation can vary by context, often reflecting the general idea of a non-negative vertical magnitude rather than a specific formal definition.
