Description

• 

The HasVowel(s) command tests whether any character in its argument s is an English language vowel.

  

The vowels are, by definition, the ten characters a, e, i, o, u, A, E, I, O and U. No other character is a vowel. In particular, the characters y and Y are not considered to be vowels for this test.

• 

If any character of the string s is a vowel character, then the value true is returned. Otherwise, the value false is returned.

Thread Safety

• 

The StringTools[HasVowel] command is thread-safe as of Maple 15.
