How to perform round to even with floating point numbers

The most basic form of rounding is to replace an arbitrary number by an integer. All the following rounding modes are concrete implementations of an abstract single-argument "round()" procedure. These are true functions (with the exception of those that use randomness). These four methods are called directed rounding, as the displacements from the original number x to the rounded value y are all directed toward or away from the same limiting value (0, +∞, or −∞… WebDec 23, 2008 · The round_to_nearest enum in doesn't help, as it doesn't clarify the IEEE round-to-even style (ties-to-even or ties-away-from-zero), even if it wasn't hard-coded...
