ASIN(3F)                             SysV                             ASIN(3F)



NAME
     asin, dasin - FORTRAN arcsine intrinsic function

SYNOPSIS
     real r1, r2
     double precision dp1, dp2

     r2 = asin(r1)

     dp2 = dasin(dp1)
     dp2 = asin(dp1)

DESCRIPTION
     asin returns the real arcsine of its real argument.  dasin returns the
     double-precision arcsine of its double-precision argument.  The generic
     form asin may be used with impunity as it derives its type from that of
     its argument.
