There is an input that I need to read from the console as a string, then manipulate the string and convert some of it to float32.
I have tried using:
float, _ := strconv.ParseFloat(myString, 32)
But it does not work. This is the error I get:
cannot use float (type float64) as type float32 in field value
Is there anything else I could do? Thanks!

We can convert a string to float in Python using the float() function. This is a built-in function used to convert an object to a floating point number.
For converting strings to floating-point values, we can use Float. parseFloat() if we need a float primitive or Float. valueOf() if we prefer a Float object.
We can convert String to float in java using Float. parseFloat() method.
To convert, or cast, a string to an integer in Python, you use the int() built-in function. The function takes in as a parameter the initial string you want to convert, and returns the integer equivalent of the value you passed. The general syntax looks something like this: int("str") .
float has the type float32, but strconv.ParseFloat returns float64. All you need to do is convert the result:
// "var float float32" up here somewhere
value, err := strconv.ParseFloat(myString, 32)
if err != nil {
// do something sensible
}
float = float32(value)
Depending on the situation, it may be better to change float's type to float64.
