Sesquillion

is a large noninteger defined by SuperJedi224 as equaling 103*1.5+3 = 107.5 ≈ 31622776.60168Almost Infinite. The name is derived from the prefix "sesqui-", meaning one and a half, and the suffix "-illion" as defined in the short scale. It is equal to the square root of one quadrillion.
The same name has also been suggested by John Savard as a long scale name for the short scale billionhttp://mathforum.org/kb/message.jspa?messageID=496158, which is equal to 106*1.5. It would be the 1.5th -illion in the long scale.
