These operators introduce very interesting properties and results: (i) faster evaluation than the exact counterpart with a negligible accuracy degradation; (ii) an efficient ALU emulation of a number of Posits operations; and (iii) the possibility to vectorize operations in Posits, using existing...
OutRas = Raster("InRas1") + Raster("InRas2") Diskussion Bei Verwendung eines Operators mit einem Eingabe-Raster ist das Ergebnis ein Raster. Wenn jedoch alle Eingaben Zahlen sind, dann ist das Ergebnis ebenfalls eine Zahl. Wenn in einem Ausdruck mehrere Operatoren verwendet werden, werden si...
While you may be tempted to quickly gloss over this guide on image arithmetic and move on to more advanced topics, I strongly encourage you to read this tutorial in detail. While simplistic, image arithmetic is used in many computer vision and image processing applications (whether you realize ...
Other interesting operators that require 0 exponent bits are the double and half functions. It is clear that, given these requirements, it is not always easy to derive a simple expression for a particular function that can be implemented in an L1 way. However, the effort put in this step ...
In this sense, it is possible to link the questions in a chain because they refer to the same conceptual field [22], i.e., they belong to the same set of reference situations, the same set of invariant operators, and the same set of language representations. Because of this peculiarity...

For more information, see the operator precedence table in Work with operators in Map Algebra. You can use parentheses to control the execution order. The order of the input is irrelevant for this operator. If both input values are integers, the output values will be integers; otherwise, the...

When there are multiple operators in an expression, the operators are not necessarily run in left-to-right order. The operator with the highest precedence value will be run first. For more information, see the operator precedence table inWork with operators in map algebra. Use parentheses to co...
