The toFixed()
method formats a number using fixed-point notation.
numObj.toFixed([digits])
digits
A string representation of numObj
that does not use exponential notation and has exactly digits
digits after the decimal place. The number is rounded if necessary, and the fractional part is padded with zeros if necessary so that it has the specified length. If numObj
is greater than 1e+21
, this method simply calls numObj.toString() and returns a string in exponential notation.
digits
is too small or too large. Values between 0 and 20, inclusive, will not cause a RangeError. Implementations are allowed to support larger and smaller values as well.toFixed
var numObj = 12345.6789; numObj.toFixed(); // Returns '12346': note rounding, no fractional part numObj.toFixed(1); // Returns '12345.7': note rounding numObj.toFixed(6); // Returns '12345.678900': note added zeros (1.23e+20).toFixed(2); // Returns '123000000000000000000.00' (1.23e-10).toFixed(2); // Returns '0.00' 2.34.toFixed(1); // Returns '2.3' -2.34.toFixed(1); // Returns -2.3 (due to operator precedence, negative number literals don't return a string...) (-2.34).toFixed(1); // Returns '-2.3' (...unless you use parentheses)
