Limitations Sq and Sq+1 must be in the same data area.
Description When
the execution condition is OFF , ROOT(72) is not executed. When the exe -
cution condition is ON, ROOT(72) computes the square root of the eight-digit
content
of Sq and Sq+1 and places the result in R. The fractional portion is trun -
cated.
R

Flags ER: Sq is not BCD.
Indirectly
addressed DM word is non-existent. (Content of ∗ DM word is
not BCD, or the DM area boundary has been exceeded.)
EQ: ON when the result is 0.
Example The
following example shows how to take the square root of a four-digit number
and then round the result.
First the words to be used are cleared to all zeros and then the value whose
square
root is to be taken is moved to Sq+1. The result, which has twice the num -
ber
of digits required for the answer (because the number of digits in the original
value was doubled), is placed in DM 0102, and the digits are split into two dif fer-
ent
words, the leftmost two digits to IR 01 1 for the answer and the rightmost two
digits to DM 0103 so that the answer in IR 01 1 can be rounded up if required. The
last step is to compare the value in DM 0103 so that IR 01 1 can be incremented
using the Greater Than flag.
