v?Rint

Computes a rounded integer value in the current rounding mode.

Syntax

call vsrint( n, a, y )

call vmsrint( n, a, y, mode )

call vdrint( n, a, y )

DOUBLE PRECISION, INTENT(OUT) for vdrint, vmdrint

Array that specifies the output vector y.

The v?Rint function computes a rounded floating-point integer value using the current rounding mode for each vector element.

The rounding mode affects the results computed for inputs that fall between consecutive integers. For example:

f(0.5) = 0, for rounding modes set to round to nearest round toward zero or to minus infinity.
f(0.5) = 1, for rounding modes set to plus infinity.
f(-1.5) = -2, for rounding modes set to round to nearest or to minus infinity.
f(-1.5) = -1, for rounding modes set to round toward zero or to plus infinity.
