How to use the function Math.log10() to get the base 10 logarithm of a number in JavaScript

Answer 1

document.write("Math.log10(0) = " + Math.log10(0) + "<br />");
document.write("Math.log10(1) = " + Math.log10(1) + "<br />");
document.write("Math.log10(-1) = " + Math.log10(-1) + "<br />");
document.write("Math.log10(2) = " + Math.log10(2) + "<br />");
document.write("Math.log10(-2) = " + Math.log10(-2) + "<br />");
document.write("Math.log10(5) = " + Math.log10(5) + "<br />");
document.write("Math.log10(10) = " + Math.log10(10) + "<br />");
document.write("Math.log10(100) = " + Math.log10(100) + "<br />");
document.write("Math.log10(100000) = " + Math.log10(100000) + "<br />");
document.write("Math.log10(125) = " + Math.log10(125) + "<br />");
document.write("Math.log10(125)/Math.log10(5) = " + Math.log10(125)/Math.log10(5) + "<br />");
