  27.      The following trigonometric functions are defined for _cccc_oooo_mmmm_pppp_llll_eeee_xxxx, where:
  28.       - _x and _y are of type _cccc_oooo_mmmm_pppp_llll_eeee_xxxx.
  29.  
  30.      _y _==== _ssss_iiii_nnnn_((((_x_))))     Returns the sine of _x.
  31.  
  32.      _y _==== _cccc_oooo_ssss_((((_x_))))     Returns the cosine of _x.
  33.  
  34.      _y _==== _ssss_iiii_nnnn_hhhh_((((_x_))))    Returns the hyperbolic sine of _x.
  35.  
  36.      _y _==== _cccc_oooo_ssss_hhhh_((((_x_))))    Returns the hyperbolic cosine of _x.
