Buenos dias, Damian.
I get 23976 x 99999 = 2397576024
x0 VAR Word ' up to 23976
y0 VAR Word ' y1:y0 up to 999999
y1 VAR bit ' the high bit of y1:y0
z0 VAR Word ' result, z1:z0
z1 VAR Word
' y1:y0 is binary code
' 99999 * 23976 < 2^32
' the product will always fit in 32 bits
x0 = 23976
y0=34463
y1=1 ' 1 * 65536 + 34463 = 99999
z0= x0 * y0 ' low word of product
z1= (x0**y0) + (x0*y1) ' high word, no carry
' one cross-term, from x0*y1
DEBUG DEC z1,tab ,DEC z0,CR ' 36584*65536+7000=2397576024
GOSUB showdubdec10 ' kick out the digits 2397576024
The routine showdubdec10 is found at this URL:
http://www.emesystems.com/BS2math6.htm#showdubdec
That routine stores the intermediate 10 digit ascii decimal result
in scratchpad RAM before printing it.
I hope that helps,
