NAME
acos, dacos - Fortran arccosine intrinsic function
SYNOPSIS
real r1, r2
double precision dp1, dp2
r2 = acos(r1)
dp2 = dacos(dp1)
dp2 = acos(dp1)
DESCRIPTION
acos returns the real arccosine of its real argument. dacos
returns the double-precision arccosine of its double-
precision argument. The generic form acos may be used with
impunity as its argument will determine the type of the
returned value.
