FCVTZU (scalar, integer)

Floating-point convert to unsigned integer, rounding toward zero.

Syntax

FCVTZU Wd, Sn ; Single-precision to 32-bit

FCVTZU Xd, Sn ; Single-precision to 64-bit

FCVTZU Wd, Dn ; Double-precision to 32-bit

FCVTZU Xd, Dn ; Double-precision to 64-bit

Where:

Wd

Is the 32-bit name of the general-purpose destination register.

Sn

Is the 32-bit name of the SIMD and FP source register.

Xd

Is the 64-bit name of the general-purpose destination register.

Dn

Is the 64-bit name of the SIMD and FP source register.

Operation

Rd = unsigned_convertToIntegerExactTowardZero(Vn), where V is either D or S.
