Degrees minutes seconds in Excel IME:ALT+41443 stands for "°"ALT+41444 stands for "the"ALT+41445 stands for "the"Excel degrees Seconds to decimal method:=left (m40,3) +mid (M40,find ("°", M40) +1,2)/60+mid (M40,find ("'", M40) +1,2)/3600Note: (m40,3) the degree has 3 digits, the same as seconds. The second digit is still counted as a decimal.MID: Returns a special number of characters starting at the specified position in the text stringExcel decimal conversion to degrees minutes seconds method:

At the beginning of this topic, there is no idea, after all, double type to retain 16 decimal places. After looking at other people's ideas to find that we should simulate the process of fractional division, in the process of simulation if the remainder has already appeared in the previous, then it will be here to form a circular section; This topic is a bit more than the pit is the output format, I was on the top of the WA several rounds.The code is as follows:/*id:15674811Lang:c++prog:fracdec*

, because the range of float values is usually larger than the integer. Example 1. Floor () example echo floor (4.3); 4 echo Floor (9.999); 9 ?> Three, round-the floating-point number rounding Description Float round (float val [, int precision]) Returns the result of rounding Val based on the specified precision precision (number of digits after decimal point). Precision can also be negative or 0 (the default value). Example 1. Round () example Echo round (3.4); 3 Echo rou

Tags: mysq row storage data problems post data table appears MySQL popularWhen you create a MySQL data table, you often encounter storage decimals (floating point numbers), such as: Price, weight, height, etc.There are three types of storage solutions prevalent in large companies:1, the data to expand the multiples of 10 to use integer type storage purposes.For example, the price, we often divided into units for storage, that is, to expand the data 10
