Z80 Assembly 50: Floating-Point to ASCII Conversion
The Challenge of Displaying Floats In Z80 assembly, a floating-point number is stored internally across multiple bytes (e.g., 4 or 5 bytes) in a specialized format (Part 30). The screen, however, only displays ASCII characters. Converting the binary float into a series of characters (“3”, “.”, “1”, “4”) is one of the most complex tasks in 8-bit programming. The Conversion Strategy The process is too complex for a single routine and is typically broken down into four major steps: ...
