critical impact:

COTAN, DCOTAN, QCOTAN, COTAND, and DCOTAND - unavailable (CrUn311)

Problem description

The following functions exist on Tru64 UNIX but not on HP-UX:

• COTAN

• DCOTAN

• QCOTAN

• COTAND

• DCOTAND

• COTAN(X) - Produces the cotangent of X. X must be of type real; it cannot be zero. It must also be in radians, and is treated as modulo 2*pi. The result type is the same as X.

  Specific Name  Argument Type  Result Type  
  =============  =============  ===========
  COTAN          REAL(4)        REAL(4)  
  DCOTAN         REAL(8)        REAL(8)  
  QCOTAN         REAL(16)       REAL(16)  
  

• COTAND(X) - Produces the cotangent of X. X must be of type real. It must be in degrees, and is treated as modulo 360. The result type is the same as X.

  Specific Name  Argument Type  Result Type  
  =============  =============  ===========
  COTAND         REAL(4)        REAL(4)  
  DCOTAND        REAL(8)        REAL(8)  
  QCOTAND        REAL(16)       REAL(16)
