n order of a radical for folat power

Question

For radical 8 by order 3 we can write 8^(1/3)
But When the compiler executes code (1/3) says we a float number and insted 2 take we a number near to 2
Becuse this is work with 8^0.3333333333 no radical 8 by order 3
8^0.3333333333 = 1.9999999999
Radical 8 by order 3 = 2
How we can fix this bug?

Answer 1

but this is give we 0 and 8^0=1

Answer 2

Vadivelan this is not my problem
