Delphi in a Nutshell

Name

Sin Function

Syntax

function Sin(Number: Floating-point type): Extended;

Description

The Sin function computes and returns the sine of Number, which is an angle in radians. The Sin function is built-in.

Tips and Tricks

• Delphi automatically converts Integer and Variant arguments to floating point. To convert an Int64 argument to floating point, add 0.0.

• If Number is a signaling NaN, positive infinity, or negative infinity, Delphi raises runtime error 6 (EInvalidOp).

• If Number is a quiet NaN, the result is Number.
