Square Root (SQR)

Description
This function block will find the square root of the input and places the result in the OUT output. If IN
is negative, OUT= 0 then the ENO output will indicate false.
Control World - Input/Output Type
The data type in the inputs and outputs may be set as "Regular" or "Percentages".
If the Percentage option was chosen, then there are two modes of operation:
If the input was set to integer:
=
OUT 100 * IN
If the input was set to real:
=
OUT 10 * IN
Option "Regular" will make the function block operate normally, i.e. calculating the SQR function
directly.
