`VCVT`

(Vector Convert) converts each element in
a vector in one of the following ways, and places the results in
the destination vector:

from floating-point to integer

from integer to floating-point

from floating-point to fixed-point

from fixed-point to floating-point.

VCVT{}.`cond`

`type`

,`Qd`

{, #`Qm`

}`fbits`

VCVT{}.`cond`

`type`

,`Dd`

{, #`Dm`

}`fbits`

where:

`cond`

is an optional condition code.

`type`

specifies the data types for the elements of the vectors. It must be one of:

`S32.F32`

floating-point to signed integer or fixed-point

`U32.F32`

floating-point to unsigned integer or fixed-point

`F32.S32`

signed integer or fixed-point to floating-point

`F32.U32`

unsigned integer or fixed-point to floating-point

`Qd, Qm`

specifies the destination vector and the operand vector, for a quadword operation.

`Dd, Dm`

specifies the destination vector and the operand vector, for a doubleword operation.

`fbits`

if present, specifies the number of fraction bits in the fixed point number. Otherwise, the conversion is between floating-point and integer.

must lie in the range 0-32. If`fbits`

is omitted, the number of fraction bits is 0.`fbits`

Integer or fixed-point to floating-point conversions use round to nearest.

Floating-point to integer or fixed-point conversions use round towards zero.
