How to convert Int data type to Float in Golang?
In Golang, the data types are bound to variables rather than the values, which means that, if you declare a variable as int, then you can store only integer type value in it, you cant assign character or string in it unless you convert the data type to required data type.
To convert an integer data type to float you can wrap the integer with float64() or float32.
x = 5 y = 5.000000 y upto 3 decimal = 5.000 float64
Explanation: Firstly we declare a variable x of type int64 with a value of 5. Then we wrap x with float64(), which converts the integer 5 to float value of 5.00. The %.3f formats the float value upto 3 decimal points.
