```
public static double value(double x)
```
    Computes the function \( \ln \Gamma(1 + x) \) for \( -0.5 \leq x \leq 1.5 \). This implementation is based on the double precision implementation in the NSWC Library of Mathematics Subroutines, DGMLN1.
    
    Parameters:
    
    x - Argument.
    
    Returns:
    
    \( \ln \Gamma(1 + x) \)
    
    Throws:
    
    java.lang.IllegalArgumentException - if x < -0.5 or x > 1.5.
