Lua read FPU registers, how?

Code:

readDouble(ST0) == 10.0 ??


readDouble(ST[0]) == 10.0 ??


readDouble(FPU0) == 10.0 ??



what's the correct way to reference FPU registers?
I cannot figure it out... : Mad

Didn't find good documentation on this. Pls help

The FP registers are a bit tricky.
Normally you'd execute
Code:

debug_getContext(true)

so it will populate the FP0 to FP7 variables and the XMM0 to XMM15 vars as well. It returns these in the format of bytetables


The problem is that the FP registers are stored as 80 bit floats and there currently is no byteTableToExtended() function

Hummmm.
I do understand FPU regs are 80 bits long,
but what's the preferred way to manipulate bits in CE's Lua Engine?

Or perhaps experienced CE users always have a way to avoid debugging FPUs?
