Description
The GRB file type, associated with HP-48 and HP-49 series graphing calculators, stands for "GROB," which is short for "graphics object." This file format is used to store graphical data, such as images or graphical representations, that can be displayed on these calculators. GRB files allow users to transfer and share graphics between calculators or between a calculator and a computer. This capability enhances the functionality of the calculators, making them versatile tools for education, engineering, and mathematical analysis.
