Find the nearest integer to the parameter.


genType round( genType x );
genDType round( genDType x );


x - Specify the value to evaluate.


 round returns a value equal to the nearest integer to x . The fraction 0.5 will round in a direction chosen by the implementation, presumably the direction that is fastest. This includes the possibility that round ( x ) returns the same value as roundEven ( x ) for all values of x .

Version Support[edit]

round (genType) 1.3+
round (genDType) 4.0+
