TypeScript Math min()

In this chapter, we will explore the Math.min() method in TypeScript. This method returns the smallest of zero or more numbers. Understanding how to use Math.min() is useful for finding the minimum value in a set of numbers.

1. Definition

The Math.min() method returns the smallest of zero or more numbers. If no arguments are given, the result is Infinity. If any argument is not a number, the result is NaN.

2. Syntax

Math.min(value1, value2, ..., valueN);

Parameters

• value1, value2, ..., valueN: Zero or more numbers among which the smallest value is to be found.

Return Value

The method returns the smallest of the given numbers. If no arguments are provided, it returns Infinity. If any argument is NaN, it returns NaN.

3. Examples

Let's look at some examples to understand how Math.min() works in TypeScript.

Example 1: Basic Usage

In this example, we use Math.min() to find the smallest number among a set of numbers.

let result = Math.min(10, 20, 30, 40, 50);
console.log(result); // Output: 10

Example 2: Using Negative Numbers

In this example, we use Math.min() to find the smallest number among a set of positive and negative numbers.

let result = Math.min(-10, -20, -30, 5, 0);
console.log(result); // Output: -30

Example 3: Using Math.min() with Variables

In this example, we use Math.min() with variables to find the smallest value.

let num1: number = 15;
let num2: number = 25;
let num3: number = 5;
let result = Math.min(num1, num2, num3);
console.log(result); // Output: 5

Example 4: Using Math.min() with Arrays (Using Spread Syntax)

In this example, we use Math.min() to find the smallest value in an array using the spread syntax.

let numbers: number[] = [10, 20, 30, 40, 50];
let result = Math.min(...numbers);
console.log(result); // Output: 10

Example 5: Using Math.min() with No Arguments

In this example, we use Math.min() with no arguments to see the behavior.

let result = Math.min();
console.log(result); // Output: Infinity

Example 6: Using Math.min() with Non-Numeric Arguments

In this example, we use Math.min() with non-numeric arguments to see the behavior.

let result = Math.min(10, 20, "30", "forty");
console.log(result); // Output: NaN

4. Conclusion

In this chapter, we explored the Math.min() method in TypeScript, which is used to return the smallest of zero or more numbers. We covered its definition, syntax, parameters, return value, and provided several examples to demonstrate its usage. Understanding how to use Math.min() effectively can help in various mathematical calculations and scenarios where finding the minimum value is required.
