mips floating point addition code

The University major is computer shoes or many or small ones know that computers store and process numbers in binary format. They cannot be precise to floating point numbers, and javascript does not have such a method, so there will be errors during browser computing. For example, if I want to use 3.3/1.1, the answer is 3, no, but we can print out the results. We are surprised that it is 2.9999999999999996.

Addition calculation error of double-precision floating point number and its preliminary method to avoid itI first found the calculation error in MySQL's sum function. After analysis, I thought it may be related to double-precision floating-point numbers.# Include Main (){Ch

Since subtraction can actually be seen as adding a negative number, we only need to see the addition operation. The addition operation of the fract16 is accomplished by the add_fr1x16 function: #pragma inline #pragma always_inline static fract16　 add_fr1x16(fract16　 __a, fract16　 __b) { fract16　 __rval = __builtin_add_fr1x16(__a, __b); return __rval; } From here we can see that we can actually use __built

This article mainly introduces the sample code for retaining two decimal points in Javascript floating point numbers (rounded to five). You can refer to it for help. The Code is as follows: Var changeTwoDecimal_f = function (floatvar ){Var f_x = parseFloat (floatvar );If (isNaN (f_x )){Return '0. 00 ';}Var f_x = M

This article mainly introduces the JS floating-point number to keep the two-bit decimal point sample code (rounded) the need for friends can come to the reference, I hope to be helpful to everyone nbsp; Code as follows: Var changetwodecimal_f= function (Floatvar) {nbsp; nb

background: The project needs to do a two-bit decimal point of the positive and negative floating-point number processing, Requirements: non-numeric or. Characters are automatically cleared, and the. 12 is automatically patched. Previous 0 principle: Add two events to the input box, KeyUp and Blur,keyup to handle the characters that are not required in th

In the first several articles in the "Code Mystery" series, floating point numbers have appeared many times. Floating Point Numbers are called simple data types in many programming languages. In fact, floating
