Square Root of a 4-digit Number
The following example shows how to take the square root of a 4-digit number
and round off the result. This program example calculates the square root of
the 4-digit number in CIO 0010, rounds off the result, and writes it to
CIO 0011. (Basically, the 4-digit number is multiplied by 10,000 (100
2
) and the
result is divided by 100, increasing the precision of the calculation by a factor
of 100.)
