在C ++中将uint转换为float

在C ++中将uint转换为float

问题描述:

我使用ReadProcessMemory为了获得4个字节。该函数允许我将它表示为unsigned int。我想代表这是一个浮动;或者换句话说使用此uint的字节表示形式用于我的浮动。

I'm using ReadProcessMemory in order to get 4 bytes. The function allows me to represent this as an unsigned int. I wish to represent this as a float; or in other words use the byte representation of this uint for my float. I've tried casting and it does not seem to work.

示例:
字节表示:
94 4E 2D 43

Example: byte representation: 94 4E 2D 43

uint:
1127042708

uint: 1127042708

float:
173.3069458 ...

float: 173.3069458..

任何帮助都会感激。

ReadProcessMemory $ c>指向void,所以你可以指向 float

float f;
ReadProcessMemory(hProcess, lpBaseAdress, &f, sizeof(f), NULL); 

请注意,当 sizeof(unsigned int)!= sizeof float)

铸造将无法工作,因为它将取值,而不是整数的表示。

Casting won't work because it will take the value and not the representation of the integer.
