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?
ex:
"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
parseFloat("string");
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.
