------------------------------------------------------------------------------
Syntax
SQRT(<nNumber>) --> nRoot
Arguments
<nNumber> is a positive number for which the square root is to be
computed.
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.
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
