VCVT (between single-precision and double-precision)

Convert between single-precision and double-precision numbers.

VCVT is always scalar.

Syntax

VCVT{cond}.F64.F32 Dd, Sm

VCVT{cond}.F32.F64 Sd, Dm

where:

cond: is an optional condition code.
Dd: is a double-precision register for the result.
Sm: is a single-precision register holding the operand.
Sd: is a single-precision register for the result.
Dm: is a double-precision register holding the operand.

Usage

These instructions convert the single-precision value in Sm to double-precision and places the result in Dd, or the double-precision value in Dm to single-precision and place the result in Sd.

Floating-point exceptions

These instructions can produce Invalid Operation, Input Denormal, Overflow, Underflow, or Inexact exceptions.
