ASIN(3F)ASIN(3F)NAME
asin, dasin, qasin, asind, dasind, qasind - FORTRAN arcsine intrinsic
function
SYNOPSIS
real r1, r2
double precision dp1, dp2
real*16 qp1, qp2
real*4 r3, r4
real*8 dp3, dp4
real*16 qp3, qp4
r2 = asin(r1)
dp2 = dasin(dp1)
dp2 = asin(dp1)
qp2 = qasin(qp1)
qp2 = asin(qp1)
r4 = asind(r3)
dp4 = dasind(dp3)
dp4 = asind(dp3)
qp4 = qasind(qp3)
qp4 = asind(qp3)DESCRIPTION
asin returns the real arcsine of its real argument, dasin returns the
double-precision arcsine of its double-precision argument, and qasin
returns the real*16 arcsine of its real*16 argument. The absolute value
of the arguments for asin, dasin, and qasin must be less than or equal to
one. The result is in radians and is in the range -pi/2 <= result <=
pi/2. The generic form asin may be used with impunity as it derives its
type from that of its argument.
asind returns the real*4 arcsine of its real*4 argument, dasind returns
the real*8 arcsine of its real*8 argument, and qasind returns the real*16
arcsine of its real*16 argument. The absolute value of the arguments for
asind, dasind, and qasind must be less than or equal to one. The result
is in degrees and is in the range -90 <= result <= 90. The generic form
asind may be used with impunity as it derives its type from that of its
argument.
