How to convert float to string












0















I read a float from a file and will have to convert it to string. My problem here is that I am unsure of how many digits will be there after the decimal. I need to take the float exactly and convert it to string.



For ex: 

1.10 should be converted to "1.10"

Also,

1.5 should be converted to "1.5"

Can someone suggest how to go about this?





string go floating-point precision

Use strconv.FormatFloat like such:



s := strconv.FormatFloat(3.1415, 'E', -1, 64)

fmt.Println(s)


Outputs




3.1415

    Convert float to string



    FormatFloat converts the floating-point number f to a string, according to the format fmt and precision prec. It rounds the result assuming that the original was obtained from a floating-point value of bitSize bits (32 for float32, 64 for float64).




    func FormatFloat(f float64, fmt byte, prec, bitSize int) string




    f := 3.14159265
    
s := strconv.FormatFloat(f, 'E', -1, 64)
    
fmt.Println(s)



    Output is "3.14159265"




    Another method is by using fmt.Sprintf 



    s := fmt.Sprintf("%f", 123.456) 
    
fmt.Println(s)



    Output is "123.456000"

A simple yellow flag (also called the "Yellow Jack") had historically been used to signal quarantine (it stands for Q among signal flags), but now indicates the opposite, as a signal of a ship free of disease that requests boarding and inspection. A quarantine is used to separate and restrict the movement of people; it is 'a restraint upon the activities or communication of persons or the transport of goods designed to prevent the spread of disease or pests', for a certain period of time. [1] This is often used in connection to disease and illness, such as those who may possibly have been exposed to a communicable disease.
