PROPOSAL: Change the spec by adding the line to float.html:"If the floating-point rounding mode is changed within a function, it must be restored before the function exits. If this rule is violated (for example, by the use of inline asm), the rounding mode used for subsequent calculations is undefined."
But that doesn't allow for changing the rounding mode at a global level, then rerunning one's computation to determine how rounding affects their final result.
