round(number)

round() rounds the value of its number argument to the nearest integer.

The Number.format, Number.precision and format() functions all round numbers in this manner when shortening numbers during formatting. A partial integer over .50 always round up, everything else rounds down. Thus:

`\$MyNumber = round(4.0);` gives 4

`\$MyNumber = round(4.2);` gives 4

`\$MyNumber = round(4.5);` gives 5

`\$MyNumber = round(4.7);` gives 5

The round function with work on string literal or String attribute values that are just numbers:

`\$MyNumber = round("4.2");` gives 4

`\$MyNumber = round("4.7");` gives 5

`\$MyString = round(4.2);` gives "4"

`\$MyString = round(4.7);` gives "5"

`\$MyString = round("4.2");` gives "4"

`\$MyString = round("4.7");` gives "5"

There are no functions to always force a round down (floor) or up (ceiling), but these can be simulated with a bit of action code.

`\$MyNumber = 100*ceil(\$MyNumber/100);`
`\$MyNumber = 100*ceil(\$MyNumber/100);`
`\$MyNumber = 100*floor(\$MyNumber/100);`
