C convert floating point to int

问题:

I'm using C (not C++).

I need to convert a float number into an int. I do not want to round to the the nearest number, I simply want to eliminate what is after the integer part. Something like

4.9 -> 4.9 -> 4

回答1:

my_var = (int)my_var; 

As simple as that. Basically you don't need it if the variable is int.

回答2:

Use in C

int C = var_in_float; 

They will convert implicit

Thank you
