This is the standard behavior of floating point arithmetic on a
digital computer. Computers use 53-bit finite precision arithmetic.
They do not use infinite precision real numbers. Please see FAQ 7.31
for details.

The concept of equality for numbers that are represented on a computer is
frequently misapplied. Consider:
a <- seq(from=0, to=1, by=0.02)
print(a[36])
[1] 0.7
a[36] == 0.7
[1] FALSE
print(a[36], digits=22)
[1] 0.7000666134
a[36] == 0.7001
[1] TRUE
All clear?
