Module 06: Functions in C#

C# has a number of builtin functions.
This lesson includes some of the most commonly used functions.

Goals:

• Learn about Built-in functions in C#, Math functions, Parsing, Random numbers

Objectives:

• Be able to use built in functions in C#;
• Be able to use the math functions to solve a problem;
• Be able to parse a string and convert to double;
• Understand and be able to use random numbers.

Please study the material at each of the links below.

1. Microsoft Reference: C# Math Functions
2. Math Functions: C# has a number of built-in functions and constants that you can use.
3. Demonstration of Math Functions: Shows how math functions might be used
4. Drill on Math Functions Ceiling, Floor, and Round: Check your understanding of these functions
5. ToString function instead of + to concatenate: Compares using + and ToString()
