Purpose
Function to perform 'C' style picture formatting
Syntax
PRINTF(<expC>, <exp1> [,<exp2>...])
See Also
ETOS(), FPRINTF(), SPRINTF(), TOSTRING()
Description
The PRINTF() function displays a string including one or more parameters, <exp1> [,<exp2>...], formatted according to the 'C' style options specified in <expC>. Each formatting sequence is applied to the corresponding parameter in the parameter list from left to right.
| Formatting option | Description |
|---|---|
| %s | |
| %d | |
| %f | |
| %y | |
| %t | |
| %T | |
| %l | |
| %L |
Example
// When %s is specified, the corresponding argument is converted to // character format (similar to specifying etos()). // Widths correspond to the default values, e.g. numerics are 10 printf('It is %s, %s to be more precise\n',year(date()),datetime()) printf('The value of pi is %s\n',pi()) printf('They cost %s per %-s\n',$99,100) printf('Logicals can be %s or %s\n',.T.,.F.) // Formatting characters can contain a width, which will left pad with spaces printf('Right-justify and pad left: %10s this\n','Like') // Left justify by placing a '-' directly following the '%' character printf('Left-justify and pad right: %-10s this\n','Like') // %d is for numerics printf('It is %d\n',year(date())) // %t and %T are for formating datetime data types. printf('It is %d, %t to be more precise\n',year(date()),datetime()) printf('It is %d, %T to be even more precise\n',year(date()),datetime()) // %f is for floating point numerics printf('The value of pi is %f\n',pi()) // Decimal places can also be specified for numerics (%d, %f) printf('The value of pi to two decimal places is %4.2f\n',pi()) // %y is for formatting currency data types printf('They cost %y per %d\n',$99,100) printf('They cost %y per %d\n',$99,1000) printf('They cost %y per %d\n',$99,10000) //%l and %L are for formatting logical datatypes. printf('Logicals can be %l or %l\n',.T.,.F.) printf('Logicals can also be %L or %L\n',.T.,.F.)
