I have an input with a type of number. When I was testing it out, I discovered that when I typed the letter e, it appeared in the text box. Any other letter did not: the input was a number. Why is a letter allowed in this input type?

2@daniel my guess is it's because it's a valid character in floating point literals – John Dvorak Sep 04 '15 at 16:19
