      2 {{alias}}( x )
      3     Computes the cosine of a number minus one.
      4 
      5     This function should be used instead of manually calculating `cos(x)-1` when
      6     `x` is near unity.
      7 
      8     Parameters
      9     ----------
     10     x: number
     11         Input value (in radians).
     12 
     13     Returns
     14     -------
     15     y: number
     16         Cosine minus one.

     18     Examples
     19     --------
     20     > var y = {{alias}}( 0.0 )
     21     0.0
     22     > y = {{alias}}( {{alias:@stdlib/constants/float64/pi}}/4.0 )
     23     ~-0.293
     24     > y = {{alias}}( -{{alias:@stdlib/constants/float64/pi}}/6.0 )
     25     ~-0.134
     26     > y = {{alias}}( NaN )
     27     NaN
