      2 {{alias}}( x, λ )
      3     Evaluates the probability density function (PDF) for an exponential
      4     distribution with rate parameter `λ` at a value `x`.
      5 
      6     If provided `NaN` as any argument, the function returns `NaN`.
      7 
      8     If provided a negative value for `λ`, the function returns `NaN`.

     29     > y = {{alias}}( -1.0, 0.5 )
     30     0.0
     31     > y = {{alias}}( 0, NaN )
     32     NaN
     33     > y = {{alias}}( NaN, 2.0 )
     34     NaN
     35 
     36     // Negative rate:
     37     > y = {{alias}}( 2.0, -1.0 )
     38     NaN
     39 
     40 {{alias}}.factory( λ )
