CAS Syntax

Numeric( <Expression> ): Tries to determine a numerical approximation of the given expression. The number of decimals depends on the global rounding you choose in the Options Menu.; Example: Numeric(3 / 2) yields 1.5.

Numeric( <Expression>, <Significant Figures> ): Tries to determine a numerical approximation of the given expression, using the entered number of significant figures.; Example: Numeric(sin(1), 20) yields 0.84147098480789650665.

Note: If you don't specify enough digits then you can get an apparently wrong answer due to floating point cancelation.

Example: Numeric(-500000000/785398163*sin(785398163/500000000)*1258025227.19^2+500000000/785398163*1258025227.19^2,10) will give 4096 but Numeric(-500000000/785398163*sin(785398163/500000000)*1258025227.19^2+500000000/785398163*1258025227.19^2,30) will give 0.318309886345536696694580314215.
