you can simply connect a float number box to an integer one and the job is done...

like riccardo says, any other object in int mode can do that, too.

however in expr it would be [expr $i1]... which is the same as [i]...

and in case you want to trucate to float: [expr int($f1)]

This number does have a finite binary representation, but it cannot be represented exactly in a (single precision) float. A double should be able to represent it exactly. Single precision floats have a mantissa of 24 bits (only 23 of which are explicitly stored as the leading bit is implicitly 1), and an exponent of 8 bits. The remaining 1 bit stores the sign of the number. Let's try to convert 67076091 to a float and see where the problem occurs
