| 5. 4. 2. Floating-point values can be represented using e-notation |
|
|
In e-notation, a number is represented by digits, followed by an e or an E, followed by the number of times to multiply it by 10. |
|
|
This notation represents the number 31250000. |
You can get this value by converting the e-notation to a calculation: 3.125 * 10^7. |
0.00000000000000003 can be written as 3e-17. |
Here, 10 is raised to the -17 power. |
By default, JavaScript converts any floating-point number with six or more leading zeros into e-notation. |
Floating-point values are stored in a 64-bit IEEE 754 format. |
Decimal values can have up to 17 decimal places. |
After that, the values are truncated. |
