不具合の修正

• Fixed several issues related to expanding (spilling) and contracting dynamic array formulas.
  • Changing cell dependencies were not taken into account when recalculating dirty cells from dynamic array formulas.
  • Clearing dynamic array formulas that reduced in size did not work correctly.
  • Cells containing formulas with the INDIRECT function are now always treated as dynamic.
• Invalid UTF-16 surrogate sequences in comment text are now sanitized before XML generation to prevent 'XmlException'.
• Using the [@page] attribute in headers or footers did not return the next character in some cases.
• The FILTER function always returned the third parameter if it contained an error value (for example, #VALUE).
• The FACT function returned (n-1) instead of n.
• Formula inline arrays did not correctly convert scientific notation (for example, 1.0E-305) to numbers.
• Defined names could use the wrong scope when a name existed in both worksheet and workbook scope and a formula was calculated using the 'Calculate(formula)' method.
• Using the ^ operator on non-numeric values returned 0 instead of #VALUE.
• Inserting columns into an empty worksheet throw an 'ArgumentException' when inserting more than 8 columns.
• GROWTH and TREND did not handle a single-value newX parameter correctly.
