In respect to this, what is the maximum value of an unsigned 32 bit integer?

The number 4,294,967,295, equivalent to the hexadecimal **value** FFFF,FFFF_{16}, is the **maximum value** for a **32**-**bit unsigned integer** in computing.

Furthermore, what is the maximum value for integer? The number **2,147,483,647** (or hexadecimal 7FFF,FFFF_{16}) is the maximum positive value for a 32-bit signed binary integer in computing. It is therefore the maximum value for variables declared as integers (e.g., as int ) in many programming languages, and the maximum possible score, money, etc.

Similarly, you may ask, what is the maximum value of unsigned int in C?

C integer types value ranges

Type | Storage size | Maximum value |
---|---|---|

unsigned char | 1 byte | 255 |

signed char | 1 byte | 127 |

int | 2 bytes or 4 bytes | 32,767 or 2,147,483,647 |

unsigned int | 2 bytes or 4 bytes | 65,535 or 2,147,483,647 |

What is the max value of int64?

**Int64** struct. It is signed and takes 64 bits. It has minimum –9,223,372,036,854,775,808 and **maximum** 9,223,372,036,854,775,807 **value**.
