find the base 10 logarithm of a number in typescript

To find the base 10 logarithm of a number in TypeScript, we can use the Math.log10() method provided by JavaScript's built-in Math object. The log10() method takes a number as input and returns its base 10 logarithm as output.

Here's an example TypeScript function that finds the base 10 logarithm of a number:

index.ts
function findBase10Logarithm(num: number): number {
  return Math.log10(num);
}
80 chars
4 lines

We can then call this function with a number as the argument and it will return its base 10 logarithm:

index.ts
const inputNumber = 100;
const base10Logarithm = findBase10Logarithm(inputNumber);
console.log(base10Logarithm); // Output: 2
126 chars
4 lines

In this example, we pass the number 100 to the findBase10Logarithm() function, which uses the Math.log10() method to calculate its base 10 logarithm, which is equal to 2. We then log the result to the console using console.log().
