XL Fortran for AIX 8.1

Language Reference

SIN(X)

Sine function.

X
must be of type real or complex. If X is real, it is regarded as a value in radians. If X is complex, its real part is regarded as a value in radians.

Class

Elemental function

Result Type and Attributes

Same as X.

Result Value

It approximates sin(X).

Examples

SIN (1.0) has the value 0.84147098 (approximately).


Specific Name Argument Type Result Type Pass As Arg?
SIN default real default real yes
DSIN double precision real double precision real yes
QSIN REAL(16) REAL(16) yes (1)
CSIN (2a) default complex default complex yes
CDSIN (2b) double complex double complex yes (1)
ZSIN (2b) double complex double complex yes (1)
CQSIN (2b) COMPLEX(16) COMPLEX(16) yes (1)

Notes:

  1. IBM Extension: the ability to pass the name as an argument.

  2. Given that X is a complex number in the form a + bi, where i = (-1)½:
    1. abs(b) must be less than or equal to 88.7228; a is any real value.
    2. abs(b) must be less than or equal to 709.7827; a is any real value.
