|---|---|---|
n |
INTEGER, INTENT(IN) |
Specifies the number of elements to be calculated. |
a |
DOUBLE PRECISION for vdround, vmdround REAL, INTENT(IN) for vsround, vmsround DOUBLE PRECISION, INTENT(IN) for vdround, vmdround |
Array that specifies the input vector a. |
inca, incy |
INTEGER, INTENT(IN) |
Specifies increments for the elements of a and y. |

y |
DOUBLE PRECISION for vdround, vmdround REAL, INTENT(OUT) for vsround, vmsround DOUBLE PRECISION, INTENT(OUT) for vdround, vmdround |
Array that specifies the output vector y. |
The function computes a value rounded to the nearest integer for each vector element. Input elements that are halfway between two consecutive integers are always rounded away from zero regardless of the rounding mode.
