var txt; txt = "Math.log10(1) = " + Math.log10(1) + "<br>"; txt = txt + "Math.log10(10) = " + Math.log10(10) + "<br>"; txt = txt + "Math.log10(50) = " + Math.log10(50) + "<br>"; txt = txt + "Math.log10(0) = " + Math.log10(0) + "<br>"; txt = txt + "Math.log10(-1) = " + Math.log10(-1) + "<br>";
The output (value of txt) after running above script will be:
Math.log10(1) = 0 Math.log10(10) = 1 Math.log10(50) = 1.6989700043360187 Math.log10(0) = -Infinity Math.log10(-1) = NaN
