Numeric Command

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.

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.

Numeric(sin(1), 20) yields 0.84147098480789650665.

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

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.
