If you have a variable with a numeric value represented as a string, how do you convert it to a numeric type in order to use it in a mathematical function? For example, I want to convert:
x = "5"
x = 5
If the variable x contains the string “5” then this code will convert it to its number equivalent and assign it to the variable y:
y = parseInt(x);
These functions are also fairly tolerant of bad data and will convert from a string to a number for as many numeric characters as they find. For example, if you pass “5.2abc” to the parseFloat() function it’ll return the number 5.2.
