Change rem into a whole number

How can I convert a rem value to an integer?

The code snippet this.props.viewTitleContainerStyle.paddingTop returns a value of 1.00rem in the debugger. The viewTitleContainerStyle is stored as theme.sizes.Measures.Measure100. I need to convert this to an integer for comparison in another expression. Is there any way to achieve this conversion?

I attempted using parseInt but it did not work.

If you need to extract numbers from a string in JavaScript, you can leverage the power of parseInt or parseFloat. These functions will parse the input string and return the valid integer or float until they encounter an invalid character like "rem". The main difference between the two is whether you want the parsing to stop at the decimal point or include the digits after it.

var value = "1.25rem";
var intParsed = parseInt(value);
var floatParsed = parseFloat(value);

console.log("parseInt():", intParsed);
console.log("parseFloat():", floatParsed);
