     sine

SYNOPSIS
     SIN ([X=]x)
     DSIN ([X=]x)
     QSIN ([X=]x)
     CSIN ([X=]x)
     CDSIN ([X=]x)
     CQSIN ([X=]x)

     SIND ([X=]x)
     DSIND ([X=]x)
     QSIND ([X=]x)

STANDARDS
     Fortran

     Fortran extensions:  QSIN, CDSIN, CQSIN, SIND, DSIND, QSIND

DESCRIPTION
     These functions evaluate y = sin(x).

     SIN and SIND are the generic function names; the others are specifics.
     These are elemental intrinsic functions.  They accept the following
     argument:

     x         Must be of type real or complex.  For SIN, DSIN, QSIN, CSIN,
               CDSIN, and CQSIN, x must be specified in radians and is
               treated as modulo 2 * pi.  For SIND, DSIND, and QSIND, x
               must be specified in degrees and is treated as modulo 360.

     A vector version of the single-precision and double-precision SIN
     intrinsic exists and is used when -O3 is specified on the compiler
     command line.

NOTES
     The SIN, DSIN, and CSIN intrinsic function names can be passed as
     arguments; the others cannot.

     Return values differ depending on your platform.  On IRIX systems,
     SIN(x) yields NaN if |x| > 219.

     On all systems that support the IEEE standard for floating-point
     arithmetic, SIN(NaN) yields NaN.

RETURN VALUES
     SIN returns the real sine of its real arguments.

     DSIN returns the double-precision real sine of its double-precision
     real argument.

     QSIN return the quad-precision real sine of its quad-precision real
     argument.

     CSIN returns the complex sine of its complex argument.

     CDSIN returns the double-precision complex sine of its
     double-precision complex argument.

     CQSIN returns the quad-precision complex sine of its quad-precision
     complex argument.

     SIND returns the single-precision real sine of its single-precision
     real argument.

     DSIND returns the double-precision real sine of its double-precision
     real argument.

     QSIND returns the quad-precision real sine of its quad-precision real
     argument.

     The terms single precision, double precision, and quad precision
     differ depending on your platform.  For platform-specific information,
     see the TERMINOLOGY section of the INTRO_INTRIN(3I) man page.
