v?Add

Performs element by element addition of vector a and vector b.

Syntax

vsAdd( n, a, b, y );

vsAddI(n, a, inca, b, incb, y, incy);

vmsAdd( n, a, b, y, mode );

vmsAddI(n, a, inca, b, incb, y, incy, mode);

vdAdd( n, a, b, y );

vdAddI(n, a, inca, b, incb, y, incy);

vmdAdd( n, a, b, y, mode );

vmdAddI(n, a, inca, b, incb, y, incy, mode);

vcAdd( n, a, b, y );

vcAddI(n, a, inca, b, incb, y, incy);

vmcAdd( n, a, b, y, mode );

vmcAddI(n, a, inca, b, incb, y, incy, mode);

vzAdd( n, a, b, y );

vzAddI(n, a, inca, b, incb, y, incy);

vmzAdd( n, a, b, y, mode );

vmzAddI(n, a, inca, b, incb, y, incy, mode);

Special values for Real Function v?Add
Argument 1	Argument 2	Result	Exception
+0	+0	+0
+0	-0	+0
-0	+0	+0

SNAN	any value	QNAN	INVALID
any value	SNAN	QNAN	INVALID
QNAN	non-SNAN	QNAN
non-SNAN	QNAN	QNAN

Specifications for special values of the complex functions are defined according to the following formula

Add(x1+i*y1,x2+i*y2) = (x1+x2) + i*(y1+y2)

Overflow in a complex function occurs (supported in the HA/LA accuracy modes only) when all RE(x), RE(y), IM(x), IM(y) arguments are finite numbers, but the real or imaginary part of the computed result is so large that it does not fit the target precision. In this case, the function returns ∞ in that part of the result, raises the OVERFLOW exception, and sets the VM Error Status to VML_STATUS_OVERFLOW (overriding any possible VML_STATUS_ACCURACYWARNING status).
