i do have a code that contains above function
can any one tell me, in which form this constant data is being stored in the float

So you are trying to set the float value by writing the four array bytes that reside in the same memory position?
I don't think it is a very good idea, why would you want to do something like that?

Maybe these can help

To be precise, C or C++ don't rely on a specific number representation, neither for integer nor float quantities. This point is considered implementation dependent. Fixing a specific number format (nevertheless most compilers are using IEEE-754) would foil code portability.
