Numeric Command
From GeoGebra Manual
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 butNumeric[-500000000/785398163*sin(785398163/500000000)*1258025227.19^2+500000000/785398163*1258025227.19^2,30]
will give 0.318309886345536696694580314215.
