However, the final estimate of x (press

Underflow
Underflow occurs when the magnitude of a number is smaller than the
calculator can represent, so it substitutes zero. This can affect SOLVE results.
For example, consider the equation
2
1
x
whose root is infinite in value. Because of underflow, SOLVE returns a very
large value as a root. (The calculator cannot represent infinity, anyway.)
