WebDec 6, 2024 · RAND_MAX is a very small number (typically 2^16). That means that from 23 bits of the floating point you make only 15 random. The others will be probably zero. You will indeed get random numbers in uniform distribution but of low precision. For example your random generator can generate 0.00001 and 0.00002 but cannot generate 0.000017. Web1. float f = 0xFFFFFFFF; 这一句完全是错误的用法,它不会使f变量内存变为4个0xFF,因为0xFFFFFFFF根本就不是有效的float数值,编译器无从处理,如果用printf ('%x')打印f的值,结果一定不是0xFFFFFFFF。 2. 正确的用法 float f; unsigned char b [4] = {0xFF,0xFF,0xFF,0xEF}; memset (&f, 0xFF, sizeof (f));// 正确的置为0xFF的方法 memcmp (&f, b, sizeof (f));// 正确的 …
