CVTTSS2SIĀScalar Single-FP to Signed INT32 Conversion
(Truncate) (Continued)
Intel C/C++ Compiler Intrinsic Equivalent
Version 4.0 and later Intel C/C++ Compiler intrinsic:
int_mm_cvtt_ss2si(__m128 a)
int_mm_cvttss_si32(__m128 a)
Convert the lower SP FP value of a to a 32-bit integer according to the current rounding mode.
Pre-4.0 Intel C/C++ Compiler intrinsic:
_m64_m_from_int(int_i)
Version 4.0 and later Intel C/C++ Compiler intrinsic:
_m64_mm_cvttsi32_si64(int_i)
Convert the integer object i to a 64-bit __m64 object. The integer value is zero extended to 64
bits.
Pre-4.0 Intel C/C++ Compiler intrinsic:
int_m_to_int(__m64_m)
Version 4.0 and later Intel C/C++ Compiler intrinsic:
int_mm_cvtsi64_si32(__m64_m)
Convert the lower 32 bits of the __m64 object m to an integer.
Exceptions
None.
Numeric Exceptions
Invalid, Precision.
