A field eight bits long can have values ranging from 0 to 255. The second section is eight bits long, and serves as the "exponent" of the number as it is expressed in scientific notation as explained above (there is a caveat, so stick around). The number 1.01011101 * 2 5 is positive, so this field would have a value of 0. It is either 0 or 1 0 indicates that the number is positive, 1 negative. The first section is one bit long, and is the sign bit. I will make use of the previously mentioned binary number 1.01011101 * 2 5 to illustrate how one would take a binary number in scientific notation and represent it in floating point notation. The single precision floating point unit is a packet of 32 bits, divided into three sections one bit, eight bits, and twenty-three bits, in that order. Now that I'm sure the understanding is perfect, I can finally get into representation. This would be represented using scientific notation as 1.01011101 * 2 5. Similarly, binary numbers can be expressed that way as well. Second, know that binary numbers, like decimal numbers, can be represented in scientific notation.

Similarly, the binary number 101.001 is simply 1*2 2 + 0*2 1 + 1*2 0 + 0*2 -1 + 0*2 -2 + 1*2 -3, or rather simply 2 2 + 2 0 + 2 -3 (this particular number works out to be 9.125, if that helps your thinking). It works more or less the same way that the decimal point does with decimal numbers. Representationįirst, know that binary numbers can have, if you'll forgive my saying so, a decimal point.

I wrote this document so that if you know how to represent, you can skip the representation section, and if you know how to convert to decimal from single precision, you can skip that section, and if you know how to convert to single precision from decimal, you can skip that section. This document does not cover operations with floating point numbers.

It explains the binary representation of these numbers, how to convert to decimal from floating point, how to convert from floating point to decimal, discusses special cases in floating point, and finally ends with some C code to further one's understanding of floating point.

This document explains the IEEE 754 floating-point standard.
