I'm trying to compile for quadruple floats
What is your compiler's C data type for these "quadruple floats" ? I had assumed that, if a C compiler could handle "quadruple floats", it would be handling them as "long doubles" - in which case building with -Duselongdouble might do the trick.

I'm using gcc on linux. Not sure what the compiler's data type for "quadruple floats" is, though "long doubles" are 16 bytes accordint to ./Configure. It seems that (2^128) should be enough.
I have long doubles turned on, and general 64 bit turned on, but I still max out at 2^64 instead of 2^113.
Is there an additional gcc flag I can pass in that anyone knows of to get the 2^113 limit?
Thanks!
Scott

Probably worth running a C program that will printf("%d\n", sizeof(long double));
Then you'll know for sure.
What does perl -V output for this build of perl ?
Cheers,

Sorry, none. I have no knowledge on the topic.
