How can I use math functions in Delphi

Delphi includes a number of math functions in its standard library, which you can use by including the Math unit in your program and calling the functions as needed. For example

Here are some of the math functions that are available in the Math unit

• Abs Returns the absolute value of a number.
• ArcTan Returns the arc tangent of a number.
• Cos Returns the cosine of an angle.
• Exp Returns the exponential value of a number.
• Ln Returns the natural logarithm of a number.
• Round Rounds a number to the nearest integer.
• Sin Returns the sine of an angle.
• Sqrt Returns the square root of a number.

You can find more information about these functions and others in the Delphi documentation.
