ASCII art of a fish. ASCII art is a graphic design technique that uses computers for presentation and consists of pictures pieced together from the 95 printable (from a total of 128) characters defined by the ASCII Standard from 1963 and ASCII compliant character sets with proprietary extended characters (beyond the 128 characters of standard 7-bit ASCII).
Signed zero is zero with an associated sign.In ordinary arithmetic, the number 0 does not have a sign, so that −0, +0 and 0 are equivalent. However, in computing, some number representations allow for the existence of two zeros, often denoted by −0 (negative zero) and +0 (positive zero), regarded as equal by the numerical comparison operations but with possible different behaviors in ...

The slashed zero 0︀ is a representation of the Arabic digit "0" (zero) with a slash through it. This variant zero glyph is often used to distinguish the digit "zero" ("0") from the Latin script letter " O " anywhere that the distinction needs emphasis, particularly in encoding systems, scientific and engineering applications, computer ...
Usually, integers are evenly spaced on the line, with positive numbers are on the right, negative numbers on the left. As an extension to the concept, an imaginary line representing imaginary numbers can be drawn perpendicular to the number line at zero. [16]
An alternative, the slashed zero (looking similar to the letter O except for the slash), was primarily used in hand-written coding sheets before transcription to punched cards or tape, and is also used in old-style ASCII graphic sets descended from the default typewheel on the Teletype Model 33 ASR.
Negative space in art, also referred to as "air space", is the space around and between objects. Instead of focusing on drawing the actual object, for a negative space drawing, the focus is on what's between the objects. For example, if one is drawing a plant, they would draw the space in-between the leaves, not the actual leaves.
Given a raster of square pixels, this leads to every square containing a part of the line being colored. A generalization of 4-connected line drawing methods to three dimensions is used when dealing with voxel grids, for example in optimized ray tracing, where it can determine the voxels that a given ray crosses.
