> It's not important to most people One can argue that nothing is important to most people. The correct calculations involving money, up to the last cent, are in fact important for people who do them or who are supposed to use them.

And, of course, from the computer manufacturers, at least IBM cares too: https://www.ibm.com/support/pages/decimal-floating-point-users-guide-technology-preview-advance-toolchain-ibm-xl-cc-linux-131 https://www.ibm.com/support/pages/decimal-floating-point-use... Apparently, there are even processors which supports these formats in hardware. It's just still not mainstream.
