This is "By Design". The parseFloat function will only consider the parts of the string up until in reaches a non +, -, number, exponent or decimal point. Once it sees the comma it stops looking and only considers the "75" portion.

To fix this convert the commas to decimal points.

Did you add the locale to the toLocaleString function?
for example
javascript
var number = 12345.543;
number.toLocaleString('en')
if i print the above code in the console it shows "12,345.543"

You can use toFixed() to do that
var twoPlacedFloat = parseFloat(yourString).toFixed(2)

If you need performance (like in games):
Math.round(number * 100) / 100
It's about 100 times as fast as parseFloat(number.toFixed(2))

You need to replace (remove) the dots first in the thousands separator, then take care of the decimal:
function isNumber(n) {
'use strict';
n = n.replace(/\./g, '').replace(',', '.');
return !isNaN(parseFloat(n)) && isFinite(n);
}

Yes remove the commas:

Removing commas is potentially dangerous because, as others have mentioned in the comments, many locales use a comma to mean something different (like a decimal place).
I don't know where you got your string from, but in some places in the world "2,299.00" = 2.299
The Intl object could have been a nice way to tackle this problem, but somehow they managed to ship the spec with only a Intl.NumberFormat.format() API and no parse counterpart :(
The only way to parse a string with cultural numeric characters in it to a machine recognisable number in any i18n sane way is to use a library that leverages CLDR data to cover off all possible ways of formatting number strings http://cldr.unicode.org/

JavaScript parseFloat in Different Cultures: Does It Use Commas or Periods as Decimal Separators? — xjavascript.com
Short Answer: parseFloat() only recognizes periods (.) as decimal separators. Commas (,) are treated as non-numeric characters, causing parsing to stop early. The behavior is defined by the ECMAScript standard, which standardizes JavaScript.
