let 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'
2.35.toFixed(1)        // Returns '2.4'. Note it rounds up
2.55.toFixed(1)        // Returns '2.5'. Note it rounds down - see warning above
-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'
