你应该能够看到类似以下的输出: text Original float value: 123.45 Converted int value: 123 这表明float值123.456已成功转换为int值123,小数部分被丢弃了。 通过这种方法,你可以在Arduino项目中将float类型的数据转换为int类型,以满足不同的数据处理需求。
Next, we declare the float variable that will store the converted integer value. For instance, let’s call the float variable “myFloat”: float myFloat; Step 3: Perform the Conversion Finally, we perform the conversion from int to float by assigning the int variable to the float variable....
