sprintf((char*)number_buffer, "%1.17g", d); 但是咱们底层的代码不支持 g,所以这个 函数是失效的,从而导致 cJSON_AddNumberToObject 失败 通俗说法,添加整型数据,就是用 sprintf 把整型添加进去 解决办法,修改下面的函数: staticcJSON_bool print_number(constcJSON *constitem, printbuffer *constoutput_buf...
创建对象数据1 cJSON* item1 = cJSON_CreateObject(); cJSON_AddStringToObject(item1, "text","我是一个字符串数据1"); cJSON_AddNumberToObject(item1,"number",666); cJSON_AddBoolToObject(item1, "state1", cJSON_False); cJSON_AddBoolToObject(item1, "state2", cJSON_True); cJSON_Add...
TheNSNumberFormatterclass is Cocoa’s way of converting betweenNSNumberandNSStringobjects. It provides both printing (number-to-string) and parsing (string-to-number).NSNumberFormatteroffers a number of built-in “formatter styles”; these are pre-built styles that allow you to print or parse ...

NSString *string = [number stringWithNumberStyle:NSNumberFormatterCurrencyStyle]; 1. 2. 3. 4. 5. 6. 7. We would have turned 4 lines of code into 1 easy to read line of code, which is clearly a lot nicer than the “normal” way of using an NSNumberFormatter...
String myStr2 = ""; myStr2.reserve(33); // buffer holds 32 chars plus null terminator assign some text to the string: myStr1 = "ABCD"; myStr2 = "ABCD"; now I want to add trailing spaces (or the character Q) to both strings to fill up to to the...
int16_t q_add(int16_t a, int16_t b) { return a + b; } 上面的程序其实并不安全,在一般的DSP芯片具有防止溢出的指令,但是通常需要做一下溢出检测,具体如下所示; 代码语言:javascript 代码运行次数:0 运行 AI代码解释 //https://great.blog.csdn.net/ int16_t q_add_sat(int16_t a, int16...
if (err != cudaSuccess) { printf("Error: %s\n", cudaGetErrorString(err)); } 最后,为捕捉异步错误(例如,在异步核函数执行期间),请务必检查后续同步 CUDA 运行时 API 调用所返回的状态(例如 cudaDeviceSynchronize);如果之前启动的其中一个核函数失败,则将返回错误。 练习:添加错误处理 目前,01-add-...
