…ecks for NaN which is handled upstream.
1000.02! -> 1. 1007.52.pow(1000.52) overflows to Infinity. 2. exp(-1007.52) underflows to 0.0. 3. Infinity * 0.0 results in NaN.

As described in #600, the app crashes when the Gamma function is evaluated with very large inputs.
This happens because a NumberFormatException is thrown when attempting to create a BigDecimal from an infinite (Infinity) result.
To prevent this, the value is now checked for finiteness before converting it to BigDecimal, ensuring that overflow cases are handled safely instead of causing a crash.
