| 47 | <function>round</function> returns a value equal to the nearest integer to <parameter>x</parameter>.\r | |
| 48 | The fraction 0.5 will round in a direction chosen by the implementation, presumably the direction that is\r | |
| 49 | fastest. This includes the possibility that <function>round</function>(<parameter>x</parameter>) returns the\r | |
| 50 | same value as <citerefentry><refentrytitle>roundEven</refentrytitle></citerefentry>(<parameter>x</parameter>)\r | |
