使用FLT_MANT_DIG和DBL_MANT_DIG，定义于<float.h>：
#include <float.h>
#include <stdio.h>
#if FLT_RADIX != 2
#error "Floating-point base is not two."
#endif
int main(void)
{
printf("There are %d bits in the significand of a float.\n",
FLT_MANT_DIG);
printf("There are %d bits in the significand of a double.\n",
DBL_MANT_DIG);
}

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.

但是请注意，知道多少位并不能告诉您它们是哪位。同样，OP可能需要考虑在标准化IEEE-754表示中隐含的前导1位。
