But there is, for most purposes, no decimal value 7.4 in the string
"aaa67.45zzz"; and, depending on circumstances, there is no decimal
value 7.4 in the string "7.4e5", although there is one in "7.4e0".

An ill-considered or inexact question will often, but not necessarily,
get an answer inappropriate for the purpose.
