Remarks |
Each of these functions converts a numeric expression to a particular variable type. In each case, numeric_expression must be within the legal range for the result type. The numeric_expression will be rounded if necessary.
These conversion functions are rarely needed as PowerBASIC automatically performs any necessary conversions when executing an assignment statement or passing parameters. For example: e% = f# is equivalent to: e% = CINT(f#) In the case of the functions that convert to

Example |
' Calculate CINT for a series of values FOR I! = 2.4! TO 2.65! STEP 0.05! x$ = FORMAT$(I!, "0.00") + " is" + STR$(CINT(I!)) NEXT I! | ||||||||||||||||||||||||
Result |
2.40 is 2 2.45 is 2 2.50 is 2 2.55 is 3 2.60 is 3 2.65 is 3 |
