I'm doing a project related to 8051 micro controller, it is required to
handle floating point numbers to a great precision.
is there any way with which this can be done easily with 8051 or is there

Floating-point numbers of any precision are just bits. An algorithm to
manipulate them can be implemented on any architecture. However if
your application requires lots of floating-point, given no further
information, 8051 would seem to be an appallingly bad choice.

Precision or dynamic range. Floating point numbers will give
dynamic range but the same number of bits in a fixed point number
will give more precision.
