![]() (6) Convert bin to hex, oct, signed int, and unsigned int. (5) Convert float to hex, oct, signed int, and unsigned int. If you would like to send me your words of support and appreciation, please email them to me! Don't forget to email me your feedback and feature requests. Please share this app to other students/professors who might benefit from using it. After converting between these three number systems, you can then press on the "Apply" button to finally convert it to a floating point value. (2) The hexadecimal, octal, and binary conversion mode - this is used to convert between hexadecimal, octal, and binary representations. (1) The floating point calculator mode - this is used to explicitly convert between binary and floating point numbers. I am still working on adding full support for all the major numerical systems/representations in computer science. Limited support means that you can only perform one-way conversions. decimal)įull support means that you can perform two-way conversations between two numerical representations. This app has limited conversion support for: (2) double-precision floating point numbers (double. (1) single-precision floating point numbers (float. This app has full conversion support for: This converter also supports other numerical systems or representations including: floating point, binary, hexadecimal, octal, signed integer, and unsigned integer numbers. Another example: by long-pressing on an individual bit, this will activate an overlay that shows the user what happens when that specific bit is toggled on or off (try it out!). For example: the binary string is color coded to help students differentiate between the sign, the exponent, and the mantissa. This app is designed to help computer science and computer architecture students easily understand how a floating point value is calculated. To clarify what that means, here are the conversions it can do: This calculator supports two-way conversions. ![]() The binary representation of Pi is therefore: It can also convert the decimal number to a 32-bit and 64-bit binary string.įor example, the floating point (decimal) value of Pi is 3.14159. The value in E is 10000100, which is 132 in decimal. If the frequency reading in floating point registers are:Ĭombine 2 registers in binary format to become:Īccording to the IEEE Floating Point Standard, split the combined value according to the structure: Take frequency reading of PM700 as an example. The architecture of this number format is the following: Sį: faction (also referred to as the mantissa or significand)Ĭalculation would be = (-1)^S * 2^(E -127) * (1.F) Some meters allow reading of values directly using Modbus protocol that are in this format (see specific meter’s Modbus Register Map for more details). ![]() The most common format is a 4 byte floating point (IEEE 754) representation. ones that don't fit easily into integer formats). Internally, most Schneider PowerLogic meters use floating point representations (conforming to IEEE floating point standards) to represent large numbers (i.e. PowerLogic and ION Meters that support IEEE 754 floating point data types in Modbus registers Some Powerlogic meters represent 32-bit Modbus registers as an IEEE 754 floating point data type ![]()
