$FUNCNAME$
  SQRT()
$CATEGORY$
  NUMERIC
$SUMMARY$
   Return the square root of a positive number
$LANG_RU$
       .
$SYNTAX$
     SQRT(<nNumber>) --> nRoot
$LANG_RU$
     SQRT(<>) -->  
$ARGUMENTS$
     <nNumber> is a positive number for which the square root is to be
     computed.
$LANG_RU$
     <> -  ,    
     .
$RETURNS$
     SQRT() returns a numeric value calculated to double precision.  The
     number of decimal places displayed is determined solely by SET DECIMALS
     regardless of SET FIXED.  A negative <nNumber> returns zero.
$LANG_RU$
     SQRT()   ,   
     .       
      SET DECIMALS       SET FIXED.

     .
$DESCRIPTION$
     SQRT() is a numeric function used anywhere in a numeric calculation to
     compute a square root (e.g., in an expression that calculates standard
     deviation).

$EXAMPLES$
       These examples show various results of SQRT():

	SET DECIMALS TO 5
	//
	? SQRT(2)                 // Result: 1.41421
	? SQRT(4)                 // Result: 2.00000
	? SQRT(4) ** 2            // Result: 4.00000
	? SQRT(2) ** 2            // Result: 2.00000
$LANG_RU$
            SQRT():

       SET DECIMALS TO 5
       //
       ? SQRT(2)                     // : 1.41421
       ? SQRT(4)                     // : 2.00000
       ? SQRT(4) ** 2                // : 4.00000
       ? SQRT(2) ** 2                // : 2.00000
