Javascript parse float is ignoring the decimals after my comma

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.

var fullcost = parseFloat($("#fullcost").text().replace(',', '.'));
