26 /* The C standard library has functions round()/rint()/nearbyint() that round
27 * their arguments according to the rounding mode set in the floating-point
28 * control register. While there are trunc()/ceil()/floor() functions that do
29 * a specific operation without modifying the rounding mode, there is no
30 * roundeven() in any version of C.
32 * Technical Specification 18661 (ISO/IEC TS 18661-1:2014) adds roundeven(),
33 * but it's unfortunately not implemented by glibc.
35 * This implementation differs in that it does not raise the inexact exception.
37 * We use rint() to implement these functions, with the assumption that the
38 * floating-point rounding mode has not been changed from the default Round
