Problem # 21 : Exponential raise
Write a function RAISE(x
y) which returns the value of x raised to the power of y.
'x' and 'y' may be any real numbers. Return 0 if the solution is not defined
ie
if x=0 and y=0.
Do this without the inbuilt procedures in your compiler (eg: POW function in C++ carat ^ sign in Qbasic etc.!) ... Duh!
Sample Output
| RAISE(2 3) | returns 8 |
| RAISE(2 .5) | returns 1.414214 |
| RAISE(27 .33333333) | returns 3 |
| RAISE(-2 3) | returns -8 |
| RAISE(99 0) | returns 1 |
| RAISE(4 -1) | returns 0.25 |
| RAISE(0 99) | returns 0 |
