COT, DCOT - Computes cotangent
UNICOS and UNICOS/mk systems:
COT ([X=]x)
UNICOS, UNICOS/mk, and IRIX systems:
DCOT ([X=]x)
UNICOS, UNICOS/mk, and IRIX systems
Compiler extension to Fortran 90
COT is the generic function name. COT and DCOT are elemental
functions for the CF90 compiler.
These functions evaluate y = cot(x).
CAL Register Usage (Cray Research Systems Only)
Scalar COT: COT% (call-by-register)
on entry (S1) = argument
on exit (S1) = result
Vector COT: %COT% (call-by-register)
on entry (V1) = argument vector
on exit (V1) = result vector
Scalar DCOT: DCOT% (call-by-register)
on entry (S1) and (S2) = argument
on exit (S1) and (S2) = result
Vector DCOT: %DCOT% (call-by-register)
on entry (V1) and (V2) = argument vector
on exit (V1) and (V2) = result vector
Argument 2R5ange
|x| < 2
25
On UNICOS/mk systems, |x| < pi * 2
DCOT:
45
|x| < 2
DCOT is an outmoded routine for the CF90 compiler. Refer to the
Fortran Language Reference Manual, Volume 3, publication SR-3905, for
information about outmoded features and their preferred standard
alternatives.
The name of this intrinsic can be passed as an argument.
COT returns the real cotangent of its real argument.
DCOT returns the double-precision cotangent of its double-precision
argument.
On CRAY T90 systems that support IEEE arithmetic, the following return
values occur:
25
COT(x) = NaN if |x| > 2 * pi or x = NaN
