On the one hand it appears not to be a problem but on the other hand could

It's probably just you not understanding what floating point numbers are.
Go read http://en.wikipedia.org/wiki/IEEE_754-2008
Also, be careful about what you call "accurate." Try the following C program:
#include<stdio.h>
int main(void)
{
int anInt = 19088743;
float aFloat = 19088.743;
printf("The integer is %i and the float is %f\n", anInt, aFloat);
return 0;
}
It prints
The integer is 19088743 and the float is 19088.742188
which doesn't even round off to 19088.743. The real question with floating point is: How many bits are required for the significand?
