normalized :: Text -> Text Source #
Normalize the input by
- removing non-word characters, except for spaces and commas; and
- converting alphabetic characters to lowercase.
:: Int | Length of the substring |
-> Int | The character offset m |
-> Text | The input string |
-> Text | A substring of length n |
Return n characters starting from offset m in the input string.
enclosedIn :: Text -> Char -> Text Source #
Insert a character at the beginning and end of the given string.
norm :: (Integral a, Floating b) => [a] -> b Source #
Returns the euclidean norm, or magnitude, of the input list interpreted as a vector.
That is,
\( \quad \sqrt{ \sum_{i=0}^n a_i^2 } \)
for the input
\( \quad \langle a_0, a_1, \dots, a_n \rangle \)
where \( a_i \) is the element at position i in the input list.
