The ADCs often used there have typical bit widths of 12 to 24 bit (e.g. 24 bit for audio). So there are definitely areas of application for Forth and small floats (after de-/normalization). In some PLC/DCS, float24 is the usable width of a 32-bit word, whereby the 8 free bits are used as binary companions, e.g. for measured value over limit.
