Parameters

Parameter

Description

number

Angle, in radians for which to calculate the sine.

Usage

The range of the result is -1 to 1. To convert degrees to radians, multiply degrees by p/180. To convert radians to degrees, multiply radians by 180/p.

Note: Because the function uses floating point arithmetic, it returns a very small number (such as 6.12323399574E-017) for angles that should produce 0. To test for a 0 value, check whether the value is less than 0.0000000000001.

Example

<cfscript>
    val=0.5
    writeOutput("The sin of " & val & " is: " & sin(val))
</cfscript>

Output

The sin of 0.5 is: 0.479425538604
