Hi guys,
Why the NNMARK is define to 0x7FF7A500? I have read the ieee 754-2008
std, the std just say that NaN's are represented by a bit pattern with
an exponent of all 1s and a non-zero mantissa. 0x7FF7A500 in binary
format is 0(sign bit) 11111111111(exponent of all 1s) 0(snan) 111 1010
0101(why?) 0000 0000. Can anyone answer my question? thanks.
