A real data type is float. Therefor float, double, long double re real data types. |

Is long int not real data type ? |

Sri said: (Apr 24, 2012) | |

long int is not real datatype. int gives a round vaule |

The floating point data types are called real data types. Hence float, double, and long double are real data types. |

What is the need of giving (unsigned char) p[i] ? |

Why it is called real data type? |

Smiline Jeba said: (Jan 30, 2013) | |

Because it gives the real value. Ex 2/5=2.50 it is the real value. It calculate the value accurately. If am wrong. Please correct me. |

Ajay said: (May 8, 2013) | |

float, double and long double called real data type because it's compute real value of any number. For Example if we want to get accurate output suppose A = 2.3 and B = 3.2 and C, Thus, C = A +B; We get 5.500000; Hence its called a real data type. |

Could you explain me what is deference between double and long double real data type? |

Can you explain the difference between float, double and long double? |

int main(){ float x; x=(float)3.3==3.3; printf("%f",x); return 0; } Ans 0.00 int main(){ float x; x=(float)3.5==3.5; printf("%f",x); return 0; } Ans 1.00 How it is possible please anyone could you explain please? |

#include<stdio.h> int main(){ float x; x=(float)4.2==(float)4.2; printf("%f",x); x=(float)3.5==3.5; printf("\n%f",x); return 0; } Answer: 1.00 1.00 This one works. I just converted both no into float. I just cannot figure out exactly why this is happening. Hope someone can figure out. |

How the output came like this? |

Sachin said: (May 8, 2015) | |

Anyone could explain me how this code has worked? |

Anusha said: (Jun 18, 2015) | |

I do not exactly. But I think this concept follows partial initialization, full initialization, null initialization. If I'm wrong any explain me the concept. |

Very good example given by all of you. Thanks for your time. |

Akshay said: (Jul 13, 2017) | |

@Akshay. Just use like Logical Operators (float)4.2==(float)4.2 is equal, so that's true and prints 1, as float, 1.0000000. |
