I have an input field that accepts numeric values. I'd like to find a method that converts that that string value into a number value.
ParseInt() was what first came to find, then toFixed().
What do these have in common? It rounds the values to its Integer value (like ParseInt suggests--I know!).
How can I convert a string representation into a number value while retaining any decimal values?
"54.3" --> 54.3
An integer is a whole number.
A Float is a number with decimal values.
Knowing this you will want to use
parseFloat(), not which will take the period into consideration, instead of
parseInt() which will round to the nearest whole number
Refer to: these docs for more detailed information
let a = "54.3"
a = +a;
Doing +a is practically the same as doing a * 1; it converts the value in
a to a number if needed, but after that it doesn't change the value.
