[P1W4] Typo in example

[ljleppan]

In 21.12 CONTOLLING THE NUMBER OF DECIMALS WHEN PRINTING A FLOAT i assume there's a typo,
"If value is a float number, the command String.value( "%.2f", value ) returns a string where the value is rounded to contain 2 decimals. The number between dot and f defines the amount of decimals shown."

The bolded part should instead be "format"
