PIC Microcontoller Math Library Methods

Conversion of Millimeters to Inches

To convert Millimeters to Inches, Divide by 25.4 or multiply by .03937.

See http://www.piclist.com/cgi-bin/constdivmul.exe

For an eight bit value...

; ACC = ACC * 0.03937
; Temp = TEMP
; ACC size = 8 bits
; Error = 0.5 %
; Bytes order = little endian
; Round = no

; ALGORITHM:
; Clear accumulator
; Add input / 32 to accumulator
; Add input / 128 to accumulator
; Add input / 4096 to accumulator
; Move accumulator to result
;
; Approximated constant: 0.0393066, Error: 0.160933 %

;     Input: ACC0, 8 bits
;    Output: ACC0, 4 bits
; Code size: 20 instructions
