parse Int

Turn text that has just number characters into a real number value. The number is an integer.

parseInt("0");

The text needs to have only number characters. This can also include the '-' and the '.' symbols though. But, only the integer part (left of the decimal point) is converted to a number.

If the text has other characters, like "-2g5u7", only -2 is returned since it is the best attempt at converting to a number. So, try not to mix number characters with letters or other symbols.

Returns

• a number value for the text number in the string.

Example

Take the temperature text from the sentence and turn it into a number.

let frozenWater = "The freezing temprature of water is 32 degrees Fahrenheit.";
let freezing = parseInt(frozenWater.substr(36, 2));
