Arduino: Превръщане на флоат в низ – ето как

by Corinna

Често, когато програмирате с Arduino, се случва да трябва да преобразувате float в string.

Arduino: Float в String – ето как

В следващите инструкции предполагаме, че вече сте дефинирали променлива float. Това може да стане например с командата „float floatvariable = 12.4;“.

  • За да присвоите символния низ на float към променливата string, просто изпълнете командата „String stringvariable = String(floatvariable);“
  • Внимание: String трябва да се записва с главна начална буква в декларацията.
  • По този начин можете лесно да преобразувате числата с плаваща запетая в низове и да ги извеждате на дисплея, например.
