| # Float Comparison | ||
|
|
||
| ## __m128i __lsx_vfcmp_cond_s (__m128 a, __m128 b) | ||
|
|
||
| ### Synopsis | ||
|
|
||
| ```c++ | ||
| __m128i __lsx_vfcmp_cond_s (__m128 a, __m128 b) | ||
| #include <lsxintrin.h> | ||
| Instruction: vfcmp.cond.s vr, vr | ||
| CPU Flags: LSX | ||
| ``` | ||
| `cond` can be one of: | ||
| - `caf`: Quiet Always False | ||
| - `ceq`: Quiet Equal | ||
| - `cle`: Quiet Less than or Equal | ||
| - `clt`: Quiet Less than | ||
| - `cne`: Quiet Not Equal | ||
| - `cor`: Quiet Ordered | ||
| - `cueq`: Quiet Unordered Equal | ||
| - `cule`: Quiet Unordered Less than or Equal | ||
| - `cult`: Quiet Unordered Less than | ||
| - `cun`: Quiet Unordered | ||
| - `cune`: Quiet Unordered Not Equal | ||
| - `saf`: Signaling Always False | ||
| - `seq`: Signaling Equal | ||
| - `sle`: Signaling Less than or Equal | ||
| - `slt`: Signaling Less than | ||
| - `sne`: Signaling Not Equal | ||
| - `sor`: Signaling Ordered | ||
| - `sueq`: Signaling Unordered Equal | ||
| - `sule`: Signaling Unordered Less than or Equal | ||
| - `sult`: Signaling Unordered Less than | ||
| - `sun`: Signaling Unordered | ||
| - `sune`: Signaling Unordered Not Equal | ||
| ### Description | ||
| Compare single precision floating point elements from `a` and `b`, save the comparison result into `dst`. | ||
| ### Operation | ||
| ```c++ | ||
| for (int i = 0;i < 4;i++) { | ||
| if (fp_compare(cond, a.fp32[i], b.fp32[i])) { | ||
| dst.word[i] = 0xFFFFFFFF; | ||
| } else { | ||
| dst.word[i] = 0; | ||
| } | ||
| } | ||
| ``` | ||

| ### Description | ||
| Compare double precision floating point elements from `a` and `b`, save the comparison result into `dst`. | ||
| ### Operation | ||
| ```c++ | ||
| for (int i = 0;i < 2;i++) { | ||
| if (fp_compare(cond, a.fp64[i], b.fp64[i])) { | ||
| dst.word[i] = 0xFFFFFFFFFFFFFFFF; | ||
