Purpose:
Floating-point Absolute value (vector). This instruction calculates the absolute value of each vector element in the source SIMD&FP register, writes the result to a vector, and writes the vector to the destination SIMD&FP register.
Result:
float16_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
float16_t data[4] = {
-1.0f, 2.5f, -3.5f, 0.0f
};
float16_t result = vabsh_f16(a);
float16_t* res = (float16_t*)&result;
printf("Results:\n");
for (int i = 0; i < 4; i++) {
printf("%f ", (float)res[i]);
}
printf("\n");
return 0;
}Prototypes
Assembly Instruction:
FABS
Usage:
float16_t result =
vabsh_f16(
float16_t a
)
