I have an IEEE-754 16-bit float that I'd like to losslessly pack as a 16-bit unsigned integer. The easiest way of course is to just pack its bytes and ...

I suppose each half precision (16bit) number can be exactly represented in single precision (32bit). But the following experiment seems to show the ha ...

I am working on converting some software to using the fmt library, which was previously using a combination of double-conversion, iostream, and boost: ...

I have three numbers with precise representation using (32-bit) floats: I expect performing a fused-multiply-add x*y+z to return the mathematically ...

I'm looking to find the maximum overall absolute and relative error of IEEE-754 single precision representation. Sign: 1 bit, Exponent: 8 bits, Signif ...

Fixing a Lua JSON implementation, I replaced "%.14g" for number formatting with "%.17g" to counter loss of precision: Formatting 17 digits using "%.17 ...

I have a question about coverting number with IEEE 754 standart. But I have 24 bits(1 bit is allocated to the sign / 7 bits are allocated to the expon ...

I want to convert a real number to his bit representation, with the fields of sign, exponent and mantissa in a VHDL TB for testing purposses (as a STD ...

I've this error on my code at the line 13 and 27, on vhdl, do anyone know what's wrong? I tried on other computers and compilers, and all got the s ...

I would like to know how to convert a float64 (or float32) to a corresponding binary/hexadecimal format. It would be great to be able to specify endia ...

I'd like to verify a piece of code works on subnormal numbers, so I'd like to generate a bunch of random subnormal single-precision numbers (including ...

I am trying to understand how numpy handles the float32 datatype. The following code produces 0.25815687 But an online float converter https://www ...

Epsilon is the smallest value in a number encoding scheme that can be added to 1 to generate a number that has a distinctly different representation. ...

The IEEE-754 standard defines subnormal numbers such that the two zeros are explicitly excluded. What's the rationale for this decision, and does this ...

The standard ways to accomplish this create more numerical precision error than is necessary. For example: Here, value_rounded does not have the ex ...

Description I need a reasonably accurate fast hyperbolic tangent for a machine that has no built-in floating point trigonometry, so e.g. the usual ta ...

It is well known floating-point computation is inexact. For example: In this case, I would like to know if there is a double number that is better ...

Given this code: let a: f64 = 0.1 + 0.2; let b: f32 = 0.1 + 0.2; let c: f32 = 0.30000000000000004; let d: f32 = 0.300000012; println!("{}", a); // 0 ...

I'm using half floats as implemented in the SoftFloat library (read: 100% IEEE 754 compliant), and, for the sake of completeness, I wish to provide my ...

Consider the following code: float value = float.MinValue; decimal dec = (decimal) value; Unhandled exception. System.OverflowException: Value w ...
