ios how to generate a int random number of float range

Question

I'm getting a random number float value:

float myFloat=120.12123123123;
int tmpInt = floorf(myFloat);
int ran=rand()%tmpInt;

But I'm trying to do everything one line:

float myFloat=120.12123123123;
int ran=rand()%([[floorf(myFloat)] intValue]);

but on this line I'm getting the following error:

"int ran=rand()%([[floorf(myFloat)] intValue]);" error : "Expeted identifier"

How can I fix this?

I'll really appreciate your help.

Answer 1

float is a primitive type, so you can just cast it. For example,

int ran = rand() % (int)floorf(myFloat);

The compiler might not even require the (int) cast...
