‘The reason this returns false is that strings are compared character by character. Since “a” comes before “c”, the characters that come after the “c” don’t matter.’

You mean the reason this returns true?

From the source:

if (r_le(beg, val)) {

if (EXCL(range)) {

if (r_lt(val, end))

return Qtrue;

}

else {

if (r_le(val, end))

return Qtrue;

}

We can understand why.

Good question! The answer is probably this bit from the documentation.

"If begin and end are numeric, comparison is done according to the magnitude of the values."

1 2	(1..9).include? 5.5 => true

Why ?
