| 2. 14. 2. Specifying Precision |
|
|
A precision specifier can be applied to the %f, %e, %g, and %s format specifiers. |
When applying to floating-point data using the %f, %e, or %g specifiers,
it determines the number of decimal places displayed. |
The default precision is 6. |
For example, %10.4f displays a number at least ten characters wide with four
decimal places. |
