result = sqrt (value)
value is any float type
Returns a floating point value with a precision equal to value
Computes the non-negative square root of the float value x. If the argument is
negative, the behavior is undefined.
Note on error handling:
If "errno.h" is included then the domain and range errors are stored in the errno
variable. The user can check the errno to see if an error has occurred and print the
error using the perror function.
Domain error occurs in the following cases:
sqrt: when the argument is negative
All devices.

distance = sqrt( pow((x1-x2),2)+pow((y1-y2),2) );
None
None
srand(n)
n is the seed for a new sequence of pseudo-random numbers to be returned by
subsequent calls to rand.
No value.
The srand() function uses the argument as a seed for a new sequence of pseudo-
random numbers to be returned by subsequent calls to rand. If srand() is then
called with same seed value, the sequence of random numbers shall be repeated. If
rand is called before any call to srand() have been made, the same sequence shall
be generated as when srand() is first called with a seed value of 1.
All devices.
