This paper is derived from quantization, data type, overflow and underflow, and the floating-point number is considered as a quantization method of real field, and the difference between floating-point number, especially irregular floating-point

PHP floating point number accuracy problem summary. PHP floating point number precision problem summary this article mainly introduces the PHP floating point number precision problem summary, this article focuses on the PHP floating point number

Binary Conversions Binary is a kind of system widely used in computing . The binary number is the number represented by 0 and 12 digits. Its base is 2, the rounding rule is "every two in one", the borrow rule is "borrowing one as two", which was

When we save the floating-point number and then read the floating-point number, the result may be a little bit biased. For example: float ft1 = 20.2; (This will cause the compiler to report a warning because the decimal point defaults to Double)

At present, the parallel optimization of the CNN convolutional neural network on the hardware platform is studied, and the relevant knowledge needs to be mended. Transferred from: http://www.cnblogs.com/kevinq/p/4480563.html Reference: 1.http://www.

One DSP Fixed-Point Arithmetic Operation1-digit CalibrationIn a fixed-point DSP chip, the number of fixed points is used for numerical calculation, and the operands are generally expressed by integer numbers. The maximum value of an integer is

Although almost every processor andProgramming LanguageAll support floating point operations, but mostProgramStaff seldom pay attention to it. This is easy to understand-most of us seldom need non-integer types. In addition to scientific computing
