Seismic modelling and inversion using half precision floating point numbers For an example showing how to use FP16 within a CUDA kernel, look at the file kernel_example.cl . It is not runnable but is a more readable version of what can be found in the full version of the code, named SeisCL . If the Armv8.2-A half-precision floating-point instructions are not available, _Float16 values are automatically promoted to single-precision, similar to the semantics of __fp16 except that the results continue to be stored in single-precision floating-point format instead of being converted back to half-precision floating-point format.

I don't know enough about Python internals, but removing precision might not help in the way you want. If you and an explanation of why you want to do this, you will likely get better answers that help you rather than just telling you how to change the value stored in a variable. – unholysampler Jun 13 '14 at 23:29 This is a decimal to binary floating-point converter. It will convert a decimal number to its nearest single-precision and double-precision IEEE 754 binary floating-point number, using round-half-to-even rounding (the default IEEE rounding mode). It is implemented with arbitrary-precision arithmetic, so its conversions are correctly rounded.
半精度浮動小数点数（はんせいどふどうしょうすうてんすう、英: half-precision floating point number ）は浮動小数点方式で表現された数（浮動小数点数）の一種で、16ビット（2オクテット）の形式によりコンピュータ上で表現可能な浮動小数点数である。 1.14. Decimals, Floats, and Floating Point Arithmetic¶ Floating point numbers like 12.345 are a basic type, but there are some complications due to their inexactness. This section may be deferred until you actually need numbers other than integers. It doesn't create a half-precision float for Python, but it does create a 16-bit (2-byte) value that Python might store for use by something else. Python can't use it as a half-precision float itself.
Scottish football wages 2018Singer model 15 partsWe will now look at some examples of determining the decimal value of IEEE single-precision floating point number and converting numbers to this form. Example 1 Consider the following floating point number presented in IEEE single precision (32 bits) as $01101011101101010000000000000000$ . I'm trying to convert a 16 bit precision binary number to decimal format however I am completely failing to do so. The binary I'm trying to convert is $0101011101010000$ My current method is:
Almost all machines today (November 2000) use IEEE-754 floating point arithmetic, and almost all platforms map Python floats to IEEE-754 “double precision”. 754 doubles contain 53 bits of precision, so on input the computer strives to convert 0.1 to the closest fraction it can of the form J /2** N where J is an integer containing exactly 53 ... Half precision floating point is a 16-bit binary floating-point interchange format. It was not part of the original ANSI/IEEE 754 Standard for Binary Floating-Point Arithmetic published in 1985 but is included in the current version of the standard, IEEE 754-2008 (previously known as IEEE 754r) which was published last August.
