For some reason I kept doing this:

DEFER(CAT(X,Y))()

That's unnecessary and just adds scans, save for very specific arguments.
The cats must be freed from their defer prisons.

  printf("trunc(-sqrt(32)): %f", FP32_CONVERT(FP32_TRUNC(FP32_NEG(FP32_SQRT(FP32_32)))));

trunc(-sqrt(32)): -6.313708

fweh. prolly just need to get its absolute value and then negate it if it was negative. time to add a FP32_WITH_SIGN as wew.

I should be more careful doing stuff like this:

#define FP32_CLASSIFY(X) CAT_ALL(_FP32_CLASSIFY, FP32_IS_NAN(X), FP32_IS_INF(X), FP32_IS_ZERO(X))

I need to pass the argument into a macro first before having its argument appear more than once.
I should check the other datatypes as well.

• FP32 cmp
• FP32 math
• FP32 bits
• U32 cmp
• U32 math
• U32 bits
• I32 cmp
• I32 math
• I32 bits
• U32H cmp
• U32H math
• U32H bits
• U64 math
• U128H cmp
• U128H math
• U128H bits
• TUPLE
• LIST
• PAIR
• BOOL

There's already a 'hex' one for hexadecimal digit operations, so there should be one for binary digit operations, instead of me copy pasting them into every binary datatype (or worse, depending on other datatypes being included and making them depend on one another unnecessarily)

those are missing. Can probably base them on trunc and do some equality and sign checking tests to get them to behave as they should. FP32_ROUND is also missing but that will be a separate issue since that one is more complicated.

Float ops are pretty slow as they are but it would be good at least for them to handle special values properly (NaN, Inf, zero)

For some reason I thought just multiplying teh exponents was enough, but actually the mantissa also needs to be multiplied, duh.

Instead of just printing the values of tests, there should be actual testing. Maybe not yet making use of a unit test library but at least checking that the results are correct and exiting/reporting otherwise.

So I don't forget, tuple foreach needs to have its eval function changed to use __VA_ARGS__, just like list foreach
