MapInfo Pro and using the "round()" function for labeling

Products affected: MapInfo Pro™, Discover™
The round() function can round numbers as needed on a temporary basis used in label expressions or other processes.

The syntax of the function is:
Round( num_expr,  round_to )
num_expr  is a numeric expression
round_to  is the number to which num_expr should be rounded off

The Round( ) function returns a rounded-off version of the numeric num_expr expression.
The precision of the result depends on the round_to parameter. The Round( ) function rounds the num_expr value to the nearest multiple of the round_to parameter. If round_to is 0.01, MapInfo rounds to the nearest hundredth; if round_to is 5, MapInfo rounds to the nearest multiple of 5; etc.

Examples for use in labeling with an expression:
Value to round = 12345.6789
Round(ColumnName, 100)  Note: This provides a new, temporary value of 12300
Round(ColumnName, 1)      Note: This provides a new, temporary value of 12346
Round(ColumnName, .01)   Note: This provides a new, temporary value of 12345.68
