Kalau [integer](\u002Fp\u002Fmengenal-tipe-data-integer-pada-java) hanya bisa menampung bilangan bulat, float ini bisa menampung bilangan pecahan juga. Contohnya: `1.5`, `2.2`, `3.14`, dan lain sebagainya.\n\n### Sub Tipe Data Float\n\nTipe data ini dapat dibagi lagi menjadi 2 berdasarkan presisinya — banyaknya angka di belakang koma, yaitu:\n\n- **float** — Tipe data berukuran 32-bit (4 byte) yang dapat menampung 6 hingga 7 angka di belakang koma. Tipe primitifnya `float` sedangkan bentuk objeknya adalah `Float`.\n- **double** — Tipe data berukuran 64-bit (8 byte) yang dapat menampung 15 hingga 16 angka di belakang koma. Tipe primitifnya `double` sedangkan bentuk objeknya adalah `Double`.\n\nBisa kita lihat, semakin tinggi presisinya semakin besar ukurannya. Karena komputer sekarang yang semakin canggih, penggunaan `double` tidak memberi perbedaan yang signifikan dibanding `float`. Namun ada baiknya untuk \"menghemat\" memori kita menggunakan `float` sebisa mungkin.\n\n### Literal Float\n\nLiteral float adalah semua angka real. Meliputi bilangan positif, negatif, bulat, pecahan, dan nol.\n\nTidak seperti lazimnya angka desimal di Indonesia yang dipisahkan dengan koma (`,`), angka desimal pada Java dipisahkan dengan titik (`.`).\n\nContohnya saja:\n\n```java\ndouble PI = 3.141592653589793; \u002F\u002F 15 angka di belakang koma\n\nfloat  tiga  = 3;   \u002F\u002F bilangan bulat\ndouble empat = 4.0; \u002F\u002F bilangan bulat\n```\n\n### Menggunakan Penanda Huruf\n\nKita juga bisa menambahkan huruf `f` atau `d` untuk menandakan bahwa bilangan tersebut merupakan float atau double. Hal ini sangat disarankan sebagai penanda tipe data suatu literal.\n\nContohnya saja:\n\n```java\nfloat  pi = 3.141592f;          \u002F\u002F akhiran `f` harus ada\ndouble PI = 3.141592653589793d; \u002F\u002F akhiran `d` opsional\n\nfloat  tiga  = 3f;   \u002F\u002F akhiran `f` opsional\nfloat  empat = 4.0f; \u002F\u002F akhiran `f` harus ada\ndouble lima  = 5d;   \u002F\u002F akhiran `d` opsional\n```\n\nSecara default Java akan membaca bilangan desimal sebagai tipe data double, oleh karena itu perlu akhiran `f` sebagai penanda bahwa literal tersebut adalah float. Jika tidak maka program akan error, karena Java tidak bisa mengkonversi double ke float data secara otomatis.\n\nDalam melakukan operasi bilangan — khususnya pembagian — tanda ini sangat penting karena dapat mempengaruhi hasil perhitungan. Akan kita bahas lebih lanjut pada bagian selanjutnya.\n\n### Menggunakan Notasi Saintifik\n\nLiteral float juga bisa dibuat dengan notasi saintifik. Kalau lupa, notasi saintifik itu yang menggunakan perkalian pangkat 10. Lebih lanjut bisa dilihat di [sini](https:\u002F\u002Fen.wikipedia.org\u002Fwiki\u002FScientific_notation).\n\nJava menggunakan notasi `e` untuk menuliskan literal. Contohnya seperti ini:\n\n```java\ndouble seribu  = 1e3;  \u002F\u002F 1 * 10^3 = 1000\nfloat  duaJuta = 2e6f; \u002F\u002F 2 * 10^6 = 2000000\n\ndouble bilanganKecil  = 7e-10; \u002F\u002F 0.0000000007\nfloat  bilanganKecil2 = 4e-5f; \u002F\u002F 0.00004\n```\n\n## Operasi pada Tipe Data Float\n\nSemua operasi yang bisa diterapkan pada integer bisa diterapkan juga pada float. Ada aritmatika, assignment aritmatika, dan juga unary operator. Lebih lanjut bisa dilihat di pembahasan [sebelumnya](\u002Fp\u002Fmengenal-tipe-data-integer-pada-java).\n\nMungkin yang sedikit membedakan adalah operasi pembagiannya. Seperti yang kita singgung sebelumnya, pembubuhan huruf `f` atau `d` dapat berpengaruh terhadap hasil perhitungan.\n\nMari kita lihat contohnya.\n\n```java\npublic class TipeDataFloat{\n  public static void main(String[] args) {\n    float a = 22;\n    float b = 7;\n    float hasil = a \u002F b;\n\n    System.out.printf(\"hasil dari %.2f \u002F %.2f adalah %.2f\", a, b, hasil);\n  }\n}\n```\n\n> Perhatian! huruf `f` di atas bukan bagian dari literal float, melainkan bagian dari template string untuk mencetak tipe data float. Lebih lanjut bisa dibaca di [sini](\u002Fp\u002Fsistem-output-pada-bahasa-java)\n\nKalau dijalankan maka hasilnya akan seperti ini:\n\n```\nhasil dari 22.00 \u002F 7.00 adalah 3.14\n```\n\nSejauh ini aman ya.\n\nSekarang kita coba isikan variabel `hasil` dengan operasi pembagian literal integer. Kita akan ubah kode di atas menjadi seperti ini:\n\n```java\npublic class TipeDataFloat{\n  public static void main(String[] args) {\n    float hasil = 22 \u002F 7;\n\n    System.out.printf(\"hasil dari 22 \u002F 7 adalah %.2f\", hasil);\n  }\n}\n```\n\nSekarang coba jalankan kode tersebut dan lihat hasilnya. Pasti hasil perhitungannya akan salah. Alih-alih mencetak angka 3.14 malah mencetak angka 3.00.\n\n```\nhasil dari 22 \u002F 7 adalah 3.00\n```\n\n**Nah loh kenapa bisa begitu?**\n\nIni karena kita menggunakan literal integer untuk melakukan pembagian. Ingat, operasi pembagian pada integer pasti akan dibulatkan, tidak bisa menghasilkan bilangan desimal.\n\nAkibatnya adalah pembagian integer 22 dan 7 — yang menghasilkan angka bulat 3 — dimasukkan ke dalam variabel `hasil`. Sehingga yang masuk ke variabel `hasil` adalah murni hasil perhitungan integer tanpa memperdulikan tipe data dari variabel `hasil`.\n\nNah untuk mengatasi masalah ini kita bisa menggunakan literal `float` dengan membubuhkan huruf `f` di belakang angka. Sehingga kodenya berubah menjadi seperti ini:\n\n```java\npublic class TipeDataFloat{\n  public static void main(String[] args) {\n    float hasil = 22f \u002F 7f;\n    \u002F\u002F bisa juga ditulis `22f \u002F 7` atau `22 \u002F 7f`\n    \u002F\u002F tapi supaya konsisten sebaiknya bubuhkan `f` di keduanya\n\n    System.out.printf(\"hasil dari 10 \u002F 8 adalah %.2f\", hasil);\n  }\n}\n```\n\n## Selanjutnya\n\nSetelah rampung 2 tipe data numerik pada Java (integer dan float), selanjutnya kita akan beralih ke tipe data yang bisa menampung huruf dan karakter.\n\nSelanjutnya kita akan membahas tentang tipe data 'char' pada bahasa Java.\n\nSemoga bermanfaat, selamat berkoding ria 👋\n","\u003Cp>Setelah mengenal tipe data \u003Ca href=\"\u002Fp\u002Fmengenal-tipe-data-integer-pada-java\">integer\u003C\u002Fa>, kali ini kita akan membahas tentang tipe data numerik lainnya, yaitu float.\u003C\u002Fp>\n\u003Ch2 id=\"tentang-tipe-data-float\">Tentang Tipe Data Float\u003C\u002Fh2>\n\u003Cp>\u003Cstrong>Floating Points\u003C\u002Fstrong> atau biasa disebut \u003Cstrong>float\u003C\u002Fstrong> merupakan tipe data standar yang dapat menampung bilangan desimal.
