GE GFK-0804B manual Division DIV, Whole # Remainder

4

Division (DIV)

The Division function divides one number by another, and places the result in two consecutive registers.

R1 B R3 = R4 46136

R1 R2 B R3 =

R4

R5

The numbers can be either constants or the contents of register locations.

When this function is programmed, only the first register of a pair is programmed; that is, the first register of the pair where the result of the division will be placed, and the first register of the number to be divided, (unless it is a constant). Although only the first register of a pair is actually specified, it is important not to use the second register for any other purpose in the program.

Examples:

				Whole #		Remainder
R1	R2		R3		R4	R5
00000	01000	/	00010	=	00100	00000	( 100 plus no remainder)
00000	01000	/	00012	=	00083	00004	( 83 plus 4 remainder)
00001	01000	/	00002	=	33268	00000	( 66536 / 2 = 33268, no remainder)
00010	01000	/	01000	=	00656	00360 (( 655360+1000) / 1000) = 656 plus
							remainder of 360)
00000	01000	/	03000	=	00000	01000	( 1000 / 3000 = 0, remainder 1000)
10000	00000	/	00010	=	00000	00000 (number is too large to represent as
							a whole number plus a remainder)
00000	01000	/	00000	= LAST RESULT (but C1023 turns on to indicate
					that a divide by 0 was incorectly attempted.
