Arduino: Float na řetězec – zde je návod, jak na to

by Tobias

Při programování s Arduinem se často stává, že musíte převést float na string.

Arduino: Při převodu floatu na řetězec: tady je návod, jak na to

V následujících instrukcích předpokládáme, že jste již definovali proměnnou float. To lze provést například příkazem „float floatvariable = 12,4;“.

  • Chcete-li přiřadit řetězec proměnné float do proměnné string, stačí provést příkaz „String stringvariable = String(floatvariable);“
  • Upozornění: String musí být v deklaraci zapsán s velkým počátečním písmenem.
  • Tímto způsobem můžete snadno převádět čísla s pohyblivou řádovou čárkou na řetězce a vypisovat je například na displej.
