Computer Graphics: Fundamental and Practice
I have every write a post and mentioned a little bit about the binary format of IEEE 754 in Comparison of Float and Double Precision. In this post I made a table to indicate the details of bit values for the IEEE 754 32bit single-precision float, the bit values of some special floating point value, [...]
When it comes to the floating point comparison with tolerance, two approaches come into my mind.
The first approach is to write inline functions and call them when compare floating point numbers. It is easy to understand and is widely used by numerous applications. Yes, it is really simple and I like it. The only concern [...]
C++ supports two primitive floating point types: float and double. These are based on the IEEE 754 standard, which defines a binary standard for 32-bit floating point and 64-bit double precision floating point binary-decimal numbers. IEEE 754 represents floating point numbers as base 2 decimal numbers in scientific notation. An IEEE floating point number dedicates [...]
