Numeric data are always calculated in up to 15 significant decimal digits; you can, however, choose to display the data in up to 6 or 15 significant decimal digits.
When entering numeric data, values greater than 106 or less than 10-6 are displayed in exponential notation. The lowercase e indicates exponential notation; however, on input, the uppercase E is also recognized. For example, you can enter 6,000,000 as 6e6 or 6E6.
To enter a hexadecimal number, precede it with 0x. For example, 0x59 is 89 decimal.
Most numeric data can be expressed using the arithmetic operators + - * / and the usual rules of precedence. For example:
2 * (5 + 4) = 18
2 * 5 + 4 = 14
2 + 5 * 4 = 22
