The sqrt function is a mathematical transformational function for REAL and COMPLEX variables.
Sqrt will return the square root of the argument passed to it. However, the argument can not be an integer type or negative.
sqrt(x)
The argument x must be of type REAL or COMPLEX.
There are no optional arguments to this function.
With real arguments, the results of the sqrt function are fairly simple. For the following lines of code:
x = 267.0 res1 = sqrt(x) res2 = sqrt (16.0)
the values of res1 and res2 are 16.34013..... and 4.0 respectively.
