Convert between floating-point numbers and integers.

Syntax

VCVT{R}{cond}.type.F64 Sd, Dm
VCVT{R}{cond}.type.F32 Sd, Sm
VCVT{cond}.F64.type Dd, Sm
VCVT{cond}.F32.type Sd, Sm
where:
R
makes the operation use the rounding mode specified by the FPSCR. Otherwise, the operation rounds towards zero.
cond
is an optional condition code.
type
can be either U32 (unsigned 32-bit integer) or S32 (signed 32-bit integer).
Sd
is a single-precision register for the result.
Dd
is a double-precision register for the result.
Sm
is a single-precision register holding the operand.
Dm
is a double-precision register holding the operand.
