Re: IEEE-754 calculation - best way?

in reply to IEEE-754 calculation - best way?

This is really 2 questions

1. How do I calculate values all adhering to IEEE-754?
2. How do I display an IEEE-754 value accurately?

Perl uses double or long double as its internal data format, depending on how it's built. It's going to do 754-compliant calculations.

The only way you can control how the value is displayed is via a mechanism that allows you to specify what you want. Things like printf/fprintf/sprintf (or something like Number::Format).
