As the max-safe-integer that can be stored in single-precision is 16777215, I chose the maximum possible fibonacci number that can be stored in single-precision to be just below this, which turns out to be 14930352. The next value after that is 24157817 , which is greater than the max-safe-integer.

Also checked it in REPL:

In [11]: float64ToFloat32(24157817)
Out[11]: 24157816

In [12]: float64ToFloat32(14930352)
Out[12]: 14930352

We do not have any precision loss for 14930352, but we do have loss for the next value, i.e., 24157817.

Hence, I chose 36 as the max-safe n.
