## Bin2Bcd3 converts Binary number to BCD

### by Vasile Surducan

```-- --------------------------------------------------
--      Bin2Bcd3(var bcd2..bcd0 , bin1..bin0)
--  converts BIN number in bin1 .. bin0
--  to BCD out bcd2 .. bcd0
--
--  bcd2:msd, bcd1:isd, bcd0:lsd, bin1:msb, bin0:lsb
-- --------------------------------------------------

Procedure AdjBcd(Byte in out digit) is
Var byte temp
var bit hc at temp : 3
var bit fc at temp : 7
temp = digit + 3
if hc then digit = temp end if
temp = digit + 0x30
if fc then digit = temp end if
End procedure

procedure bin2bcd3 (byte out bcd2,byte out bcd1,byte out bcd0,
Byte in bin1 ,Byte in bin0)  is

bcd2 = 0
bcd1 = 0
bcd0 = 0
for 16 loop			   -- all (16) bits of bin0..bin2

Assembler
rlf bin0,f
rlf bin1,f
rlf bcd0,f
rlf bcd1,f
rlf bcd2,f

End Assembler
End loop
End procedure
