why we should not apply bitwise operators on float values?

[ani507]

if we did program using using bitwise opertors for float values it i showing error

Because it makes little sense because of undefined internal representation - what would you like 1.75 & 2.5 to be?

Because the standard defines bitwise operations as only valid on integer types. No conforming compiler is likely to compile it.

What are you trying to accomplish?
Perhaps we can suggest a workable alternative if we understand the goal.
