Here is a list of the intrinsic functions in libm. You need not put them in a type statement. These functions take single, double, or quad precision data as arguments and return the same.
| sqrt(x) | asin(x) | cosd(x) |
| log(x) | acos(x) | asind(x) |
| log10(x) | atan(x) | acosd(x) |
| exp(x) | atan2(x,y) | atand(x) |
| x**y | sinh(x) | atan2d(x,y) |
| sin(x) | cosh(x) | aint(x) |
| cos(x) | tanh(x) | anint(x) |
| tan(x) | sind(x) | nint(x) |
The functions sind(x), cosd(x), asind(x), acosd(x), atand(x), atan2d(x,y) are not considered intrinsics by the FORTRAN 77 standard.
