Sir,

In case of COBOL language, if we want to raise the power e.g. we need to find out 2 raise to power 2 is how much.......means square of 2,

We can use

COMPUTE C = 2 ** 2.

this will work and after execution of this statement C will contain 4.

but if I will raise the power by decimal number, it wont work....e.g.

COMPUTE C = 4 ** (0.5).

but after execution of this statement C should contain 2....... but I am getting error.......

Kindly help me

Alright. Rewrite that a little more clearly and I'll see what I can do for you.

I think I know what you're trying to do, but I'm not totally sure.

It might be best to modify the decimal exponent.

As in, the user enters X^0.5, modify the exponent so the output is X/2?

Same with X^0.25... modified to X/4, etc, etc

As in if exp<1, then Y=1/exp and Z=X/Y?

Is this making any sense at all?

What error are you receiving? Are you getting an error at compile time? Or are you not receiving 2 as the answer for the square root of 4?

COMPUTE C = (4 ** .5)

should result in C containing 2.
