Chapter two attracts your eyeballs-ui programmingThe most straightforward way to learn about the development techniques of Android applications is to learn how to use various UI components, in addition to being familiar with the tools first. The applications we develop typically contain a set of user-visible interfaces that are made up of ANDROIDUI components. In the process of learning interface development technology, we must first familiarize ourse

Storage Method of floating point and floating point in memory, floating point First, let's talk about how to convert decimal places to binary decimal places. The computer doesn't even know the decimal data. He only knows 0 and 1. So, decimal decimal places are represented by binary decimal places in the computer. Decimal decimal to binary decimal: It can be simpl

How the Float WorksFloating is to let an element out of the flow of the document, before and after the floating box and the non-positioning elements will be in the same way, it may flow vertically along its other side, but all make room for it, block-level elements are no exception (the floating element occupies a portion of the block-level elements of the line space, is still considered to occupy a It is j

is a fractional part. The type returned by Ceil () is still float, because the range of float values is usually larger than the integer. ceil(4.3); // 输出5 ceil(9.999); // 输出10 4. Use float round (float val [, int precision]) function Rounds a floating-point number, returning the result of rounding Val based on the specified precision precision (the number of digits after the decimal point). Precision can also be negative or 0 (the default value).

Label:Floating-point numbers are saved in the following byte format: Address +0 +1 +2 +3Content seee eeee emmm MMMM MMMM MMMM MMMM MMMM Over hereS represents the sign bit, 1 is negative, 0 is positiveThe power of E offset 127, binary order = (EEEEEEEE)-127.The mantissa of the M 24 bits is stored in 23 bits, with only 23 bits, and the highest bit fixed at 1. This method is implemented with the least number of bitsHigh number of significant digits, improving the accuracy. 0 is a specific value, th

we divide the common layout format of the webpage into the following three kinds:1. Standard flow. The so-called standard flow is that the inline elements own a single line, and the block-level elements are displayed up and down.We used to learn the standard flow.Note: Standard flow makes the most stable structure in our web page layout2. Floating StreamLet us learn the first way out of the standard flow. Will affect the arrangement of our standard fl

CSS Floating 1. What is floating :A technique used in our layout that allows us to lay out the elements by letting them float, we can move the elements around horizontally, and then adjust the position with the margin property. 2.
