; routine by Lee Davison, source: http://6502.org/source/integers/square.htm
; using this routine is a lot faster as doing a regular multiplication (for words)
;
; Calculates the 16 bit unsigned integer square of the signed 16 bit integer in
; Numberl/Numberh. The result is always in the range 0 to 65025 and is held in
; Squarel/Squareh
;
; The maximum input range is only +/-255 and no checking is done to ensure that
; this is so.
;
; This routine is useful if you are trying to draw circles as for any circle
;
; x^2+y^2=r^2 where x and y are the co-ordinates of any point on the circle and
; r is the circle radius
