Exponential functions (sqrt, exp, logn )

Exponential fnctions deal with powers of numbers.

There are three functions which Logo learns from logo.eli file.

Sqrt is used to calculate squares of numbers,

exp is used to raise e to a given power (e is an important mathematical constant which is approximately 2.718 - a more precise value is calculate by exp 1).

The third function is logn and it is the reverse function for exp.
	print sqrt 3 ; 9
	print exp 1 ; 2.71828182845905
	print logn 10 ; 2.30258509299405
