9.2) List Of Intrinsic Functions
The table lists commonly used intrinsic functions. At the compilation stage the Fortran compiler provides the calculations for these functions.
| Function | Description |
| cos(x) | Cosine of x (in radians) |
| sin(x) | Sine of x (in radians) |
| tan(x) | Tangent of x (in radians) |
| exp(x) | Exponential of x |
| log(x) | Natural logarithm of x |
| log10(x) | Logarithm of x to base 10 |
| acos(x) | Inverse function of cosine of x |
| asin(x) | Inverse function of sine of x |
| atan(x) | Inverse function of tangent of x |
| int(x) | Converts a real variable x into an integer |
| real(I) | Converts an integer i into a real variable |
| sqrt(x) | Square root of x |
