Subject: [R] precision problem
I have prices that I am finding difficult to compare with ==,
and >, due to precision. For example: the numbers should
match, with '==', but they differ in the magnitude of 1e-14
due to bunch of calculations that I run on them. Programming
with java, I am used to implementing a function that compares
the difference between the numbers to a pre determined
precision factor. This could be very slow when I have two
matrices of numbers that I could otherwise compare with a
simple '==', '>' or '<' in R.
What is teh best solution for this problem?
Can I control the precision of ==, > and < without having to
reimplement the operations in a slow way?
