@code{bignum} is any integer which is not a @code{fixnum} and it is only

ECL code{@integer} subtypes @code{fixnum} and @code{bignum} are defined

In ECL a @code{fixnum} is an integer that, together with the tag bits,

In ECL @code{float} subtypes @code{single-float}, @code{double-float}
and @code{long-float} (on supporting platforms) are defined as built-in
