Saturation floating-point conversion functions

Microsoft Specific

Conversion functions between floating-point types and integral types that use an ARM processor-compatible saturation strategy.

Syntax

int _cvt_ftoi_sat(float value);
long long _cvt_ftoll_sat(float value);
unsigned _cvt_ftoui_sat(float value);
unsigned long long _cvt_ftoull_sat(float value);
int _cvt_dtoi_sat(double value);
long long _cvt_dtoll_sat(double value);
unsigned _cvt_dtoui_sat(double value);
unsigned long long _cvt_dtoull_sat(double value);

Parameters

value
[in] A floating-point value to convert.

Return value

The integer-typed result of the conversion.

Requirements

Header: <intrin.h>

Architecture: x86, x64

Remarks

These intrinsics are floating-point to integral type conversion functions that use a saturation strategy: Any floating-point value too high to fit in the destination type is mapped to the highest possible destination value. Any value too low to fit maps to the lowest possible value. And if the source value is NaN, zero is returned for the result.

The saturation conversion intrinsics are available starting in Visual Studio 2019 version 16.10.
