There appears to be a production issue in the creation of the PDF version of this DIS. Many of the mathematical formulas that define the spreadsheet functions are illegible, and all of them are of low quality. For example, 3.17.7.24, 3.17.7.32, 3.17.7.38, etc.
Provide higher resolution of the mathematical equations.

Proposed Disposition of DIS 29500 Comment US-0283 (Modified: 2007-11-15) Yes, not only are these formulas hard to read, they don’t scale at all well. These formulas will be replaced by the equivalent WordprocessingML equations. Some examples of the current formulas and their corresponding replacements using equivalent WordprocessingML are as follows: 3.17.7.2 ACCRINT = × × =1 3.17.7.24 BESSELJ = -1 ! + + 1 2 +2 =0 3.17.7.206 MDURATION = 1 + Similar Comments: CA-0047 , CL-0144 , CO-0152 , DK-0089 , ECMA-0032 , FR-0353 , FR-0412 , FR-0452 , GB-0370 , GB-0400 , US- 0197 ,

Just-fix-it.
However, it implies that it was not possible to effectively review the definitions of the spreadsheet functions, which probably should be discussed at the BRM.
They’re probably illegible as they used OOXML for writing the document?
