You can display the float numbers with the decimal place, zero-padding options, supporting the negative number: 您可以使用小数位、零填充选项显示浮点数,支持负数: display.printFloat(-9.2, 1, false); You can also display number, decimal point, character digit-by-digit by using lower-level functi...

float parseInt() Description 从新到的串口数据中查找下一个有效的整数 Looks for the next valid integer in the incoming serial stream. parseInt() inherits from the Stream utility class. In particular: Initial characters that are not digits or a minus sign, are skipped; Parsing stops when no...
floatData type for floating-point number is a number that has a decimal point. Floating-point numbers are often used to approximate the analog and continuous values because they have greater resolution than integers.Floating-point numbers can be as large as 3.4028235E+38 and as low as -...

When we want to use a value from an array, we'll need to specify which place in the array we want the value of. Let's use the array in blink7 as an example : int array[] = {1,2,3,4,5,6,5,4,3,2}; if we want to get the first value of the array, we use ...
