===== SQR ✓ =====

===== SYNTAX =====
     = SQR(expression)

==== PURPOSE ====


The ''SQR'' command (short for "square root") is a mathematical function that
is used to calculate the square root of a number. In other words, given a number
''x'', the command ''SQR(x)'' returns the number that, when multiplied by itself, 
gives the result ''x''.

The ''SQR'' command has many applications in programming: it is used in any 
calculation that requires the calculation of the square root, such as in the 
Pythagorean theorem. The square root is present in many physics formulas, 
such as in the calculation of velocity. It is used also to calculate the 
lengths of segments or areas of geometric figures, and in many statistical 
calculations, such as in the calculation of standard deviation.

The square root of a negative number is not defined in real numbers. If you 
try to calculate the square root of a negative number, the result is indefinite.
Moreover, the function is defined in the integer numbers domain.



==== EXAMPLE ====
    PRINT SNG(81)
