Why does it matter that the integer variable is 32 bits?

How many bits does the float type use?

This looks like a 17-bit integer type to me, not 32-bit.

Then it cannot hold a 32-bit integer without losing some precision,
since some of the float's 32 bits will be reserved for the exponent.
But since the integer type is only 17-bit wide, that's OK; the mantissa
of a 32-bit float is very probably wider than 17 bits.

That's a type conversion, it assigns the value 1234.0 to A_Float.  Since
you ask a question, I can only assume that that's now what you wanted.
So what is it that you want, exactly?
