Why 0.1 + 0.2 = 0.30000000000000004 (in Javascript)?

0.1 + 0.2 = 0.3, but in Javascript 0.30000000000000004. Why?

Computer can't store floating point too accurately. Use toFixed to set it to less decimal point. In equelity comparison, never apply strict equality to floating point "===", use equality "==" and adjust toFixed function instead. console.log((0.1+ 0.2)===0.3? "true":"false"); // return false console.log((0.1+ 0.2).toFixed(16)==0.3? "true":"false"); // return true
