# Procedures # Procedures
Procedures in Nimrod are declared using `proc` and require that their parameter and return types be annotated. After the types and parameters, an `=` is used to denote the start of the function body.
``` nimrod
proc fibonacci(a, b, n: int): int =
if n > 1:
result = fibonacci(b, a+b, n - 1)
else
a
```
