C Programming: Output of Float Calculation

[ubuntu2]

The question is
What will be the output?
#include<stdio.h>
int main(void)
{float y=6/4;
printf("%.1f\n",y);}
The answer is
1.0
I got that right by trusting my senses; but I want to understand why.

C does maths in the 'simplest' way possible, so 6/4 is done as an integer division = the answer is an integer which is then converted to a float.

right! integer operated by integer results in integer!
thanks a lot.
