\DOC mk_realintconst
\TYPE {mk_realintconst : num -> term}
\SYNOPSIS
Converts an OCaml number to a canonical integer literal of type {:real}.
\DESCRIBE
The call {mk_realintconst n} where {n} is an OCaml number (type {num}) produces
the canonical literal of type {:real} representing the integer {n}. This will
be of the form `{&m}' for a numeral {m} (when {n} is nonnegative) or `{-- &m}'
for a nonzero numeral {m} (when {n} is negative).
\FAILURE
Fails if applied to a number that is not an integer (type {num} also includes
rational numbers).
\EXAMPLE
{
# mk_realintconst (Int (-101));;
val it : term = `-- &101`
# type_of it;;
val it : hol_type = `:real`
}
