how to use malloc to reserve space for 1 million floats

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I want to use the following command:

int myvariable = 1000;
float *myarray = malloc(pow(myvariable,3)*sizeof(float));

but I don't know if it will work because if sizeof(float) is equal to 4 then pow(myvariable,3)*sizeof(float) is equal to 4 billion which is larger than the maximum integer which is about 2 billion.

Can you tell me what is the right way to create an array of pow(myvariable,3) floats?

Many Thanks,
Anna
