#### `plprec`: Set precision in numeric labels

`plprec (` | setp,
| prec`)`;

Sets the number of places after the decimal point in numeric labels.

`setp` (`PLINT`, input)

  If ``setp`` is equal to 0 then PLplot automatically determines the number of places to use after the decimal point in numeric labels (like those used to label axes). If ``setp`` is 1 then ``prec`` sets the number of places.

`prec` (`PLINT`, input)

  The number of characters to draw after the decimal point in numeric labels.

Redacted form: `plprec(setp, prec)`

This function is used in example 29.
