acos(3f)
NAME
acos, dacos − Fortran arccosine intrinsic function
SYNTAX
real r1, r2
double precision dp1, dp2
r2 = acos(r1)
dp2 = dacos(dp1)
dp2 = acos(dp1)
DESCRIPTION
The acos function returns the real arccosine of its real argument. The dacos function 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.
