FRINTP (scalar)

Floating-point Round to Integral, toward Plus infinity (scalar).

Syntax

FRINTP Hd, Hn ; Half-precision

FRINTP Sd, Sn ; Single-precision

FRINTP Dd, Dn ; Double-precision

Where:

Hd
Is the 16-bit name of the SIMD and FP destination register.
Hn
Is the 16-bit name of the SIMD and FP source register.
Sd
Is the 32-bit name of the SIMD and FP destination register.
Sn
Is the 32-bit name of the SIMD and FP source register.
Dd
Is the 64-bit name of the SIMD and FP destination register.
Dn
Is the 64-bit name of the SIMD and FP source register.

Operation

Floating-point Round to Integral, toward Plus infinity (scalar). This instruction rounds a floating-point value in the SIMD and FP source register to an integral floating-point value of the same size using the Round towards Plus Infinity rounding mode, and writes the result to the SIMD and FP destination register.

A zero input gives a zero result with the same sign, an infinite input gives an infinite result with the same sign, and a NaN is propagated as for normal arithmetic.

A floating-point exception can be generated by this instruction. Depending on the settings in FPCR, the exception results in either a flag being set in FPSR, or a synchronous exception being generated. For more information, see Floating-point exception traps in the ARM Architecture Reference Manual ARMv8, for ARMv8-A architecture profile.

Depending on the settings in the CPACR_EL1, CPTR_EL2, and CPTR_EL3 registers, and the current Security state and Exception level, an attempt to execute the instruction might be trapped.

Vd = roundToIntegralTowardPositive(Vn).
