sqrt
<built-in> function sqrt(object value)
calculates the square root of a number.
Parameters:
- value : an object, each atom in which will be acted upon.
Returns:
An object, the same shape as value. When value is an atom, the result is the positive atom whose square is value.
Errors:
If any atom in value is less than zero, an error will occur, as no squared real can be less than zero.
Comments:
This function may be applied to an atom or to all elements of a sequence.
Example 1:
r = sqrt(16) -- r is 4
