in reply to Re^4: Reasons for Using Perl 6
in thread Reasons for Using Perl 6
When using irrational numbers, such as square root of 2, or trigonometric functions, then Perl 6 is forced to use floating-point arithmetic and suffers from the same drawbacks as other programming languages.
So Perl 6 can do simple interest calculations accurately, but for compound interest calculations, it would fall back on floating-point arithmetic (and its flaws) for most common cases (although it is often possible to work around this if needed).
I agree with your point about Perl and speed not being necessarily mutually exclusive. Even though I am dealing with huge volumes of data (so speed is important to me), I have never needed to actually use things such as Inline::C at $work.
