Write pseudocode to prompt a user to enter their Fahrenheit temperature, convert it to Celsius, determine the fever range, and inform the user of the results.

1. Prompt the user to enter their Fahrenheit temperature as a real number.
2. Convert the temperature to Celsius using the formula:
\[
\text{Celsius} = \frac{5.0 \times (\text{Fahrenheit} - 32.0)}{9.0}
\]
3. Determine the fever range:
- No fever if Celsius is less than 38.
- Low-grade fever if Celsius is 38 or greater but less than 39.4.
- High-grade fever if Celsius is 39.4 or higher.
4. Inform the person of their Celsius temperature and the fever range it falls into.
