round — 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.
