Built-in Functions

len(a): Returns the length of array a.
re(s, x): Returns true if string s matches regular expression x.
pow(n, e): Returns n raised to the power of e. Result is int or int64 if both n and e are int or int64, otherwise float64.
toInt64(s, b=10): Parses string s in base b and returns in int64.
