Builtins

Every AHA! program gets a small set of standard builtins:

Builtin	Description
`print(int)`	Print an integer
`print_str(string)`	Print a string
`len(string)`	String length in O(1)
`abs(x)`	Absolute value
`min(a, b)`	Smaller of two numbers
`max(a, b)`	Larger of two numbers

Examples

print(42);           // 42
print_str("hello");  // hello
print(len("hello")); // 5
print(abs(-7));      // 7
print(min(3, 9));    // 3
print(max(3, 9));    // 9

Notes

print takes an integer; print_str takes a string. print("hi") is a compile-time type error — strings go through print_str.
len returns the stored length of the string struct, so it is O(1) regardless of string size.
