Rules
for
decinzal
point
Addition and subtraction. Position thc decimal indicator identically
in thc setting
and in
the
product
register.
Set
up all nurnbers with the same number of decirnals
so that
they con,e right rel:tive
to the decimal
poinr
in the setting register.
Mahiplication-
The number of decimals in the
product register is
to
bc the
same
as the sum
of
the decimals in the setting up and multiplier registers. Mark the
position
of the
decimal
point
in the
product
register according to rule before
starting calculation.
Diaision. The number of decimals in the
multiplier
rcgistcr is to be the same as
the
differcnce between the nunber of decimals in the
product
and serting up
registers. You can avoid unnecessary calculating work if
you
determine the
position
of
the
decimal
point
and how many decimals are needed in the answer
(quotient)
before
you
start to divide. See also the example at the top of the
page.
