Modelsim: Interpretation of numbers in wave window

Hello!

First of all, thanks for your effort and interest in replying!

The 64 bit sequence is a fixed fractional number, not a float number. I.e. the 32 first bits represents the number and the 32 last (LSB ) represents the fractional part, 1/2 and below.

But the most amazing thing regarding this, is that if I do the same with a 32 bit, with 16 bit integer, 16 fractional bits, then everything works perfectly.

The 32-bit sequence: 0000000000000000 . 0000000100000000 i.e. 1/128 = 0.0078125 is showed correctly with radix fixed#16#decimal#signed. (signed/unsigned does not matter, it works correctly)

See attached image.

This is nothing short of mind blowing to me, I simply can't understand it.
