SQRT
Elemental Intrinsic Function (Generic): Derives the square root of its argument.
Syntax
result = SQRT (x)
x
(Input) must be of type real or complex. If x is type real, its value must be greater than or equal to zero.
Results:
The result type is the same as x. The result has a value equal to the square root of x. A result of type complex is the principal value, with the real part greater than or equal to zero. When the real part of the result is zero, the imaginary part is greater than or equal to zero.
