== Rounding == | |||
The last step is to round these numbers down. Traditional mathematics writes ''floor'' as <math>⌊x⌋</math> but APL is regular, and no function is denoted by two separated symbols. If the function takes a single argument, then the symbol will be on the left, so we write floor as <source lang=apl inline>⌊x</source>: | |||
