Hi All, Is there an option in PHP to change the behavior of NULL in PHP functions ? Now PHP uses NULL as a 0 (zero) for arithmetic, for example: NULL + 6 = 6 NULL * 6 = 0 NULL / 6 = 0 6 / NULL = Division by zero What I need is the same behavior as #N/A (or =NA()) in Excel, where: #N/A + 6 = #N/A #N/A * 6 = #N/A #N/A / 6 = #N/A 6 / #N/A = #N/A because arithmetic operations with "Unknown" operands should result to "Unknown" ... TIA, Cor
