I believe "proper subset" is the more common form of "strict subset".

Page 3, both tables:  emax formula: right column: has 2x instead of 2**x
That is, the 'x' should be a superscript.

Page 3, both tables: emin formula:  3-emax would be better.  Some
people interpret -emax+3 as -(emax+3).  The same change would apply to
other uses of -emax+3 in the document.

Page 6, line 36: Should DEC_EVAL_METHOD 0 have words similar to 1 (eg,
subset of values of _Decimal32).

Page 8, line 3, 20:  Is that absolute value symbol or ceiling symbol?

Page 8, line 8:  Is that absolute value symbol or floor symbol?

Page 8, line 20:  Is emin-1 supposed to be the exponent of 2?  Since
log(a**b) is b*log(a), it might be clearer to use: ceiling((emin-1)*log10(2)))

Page 8, line 32, 36:  Is emax supposed to be an exponent?  Is -p supposed
to be an exponent?

Page 8, line 43:  Is 1-p supposed to be an exponent?  
Also, add "normalized" between "least" and "value".

Page 8: Need to add after FLT*MAX, a new section: FLT*_NORM_MAX (to be
consistent with C2X).

Page 9: line 1: Is emin-1 supposed to be an exponent?

Page 9: line 7: Is emin-p supposed to be an exponent?

Page 12, line 14:  Would it be better to replace (in C2X) "_Decimal32,
_Decimal64,  _Decimal128" with "_DecimalN, where N is multiple of 32".

Page 18, line 3:  Should "M<=N" be "M<N"?

Page 29, line 42: Should *exp be a superscript?

Page 29, line 44: Should exp be a superscript?

Several places:  "applys" should be "applies".

Page 32, line 32:  "delare" should be "declare".
