Floating Point to ASCII Conversion

From Microchip Technology, Inc.
 

 
It is often necessary to output a floating point number to a display. For example, to check calculations, one might want to output floating point numbers using the PICmicro ® microcontrollers serial port, or use general purpose I/O to output to a liquid crystal display (LCD). Either way, the floating point number must be con-verted to its ASCII equivalent. This document shows a specific example of converting a 32-bit floating point number to ASCII. Application note AN575 contains 24-bit and 32-bit floating point routines. A subroutine is provided here that does the conversion and returns the ASCII equivalent in RAM. An example ?main? program is provided to show how to use the subroutine
