The question is whether it makes sense to have "unchecked_*" methods
for floats and doubles. The point of "unchecked_*" methods is to
declare your willingness to get nonsense answers with fixed-width
integer operations. Floating-point operations already have semantics
that make sense for conditions like overflow, and (unlike integer
operations in Clojure) they don't switch to "bigfloats" on overflow.
If you'd like to have the methods just for completeness' sake, it
doesn't look too hard to add them. Check out src/jvm/clojure/lang/
Numbers.java and look for static methods of the form "unchecked_add",
"unchecked_multiply", etc. For each "unchecked_*" method name and for
each data type, there should be one such method: e.g.,
static public int unchecked_add(int x, int y){
return x + y;
}
static public long unchecked_add(long x, long y){
return x + y;
}
