Function Num2Str converts a REAL value to a string and returns the value.
Parameter decPlace has a range of -1 to 9; if -1 is specified, the value will be returned in scientific notation.
FUNCTION Num2Str(
decPlace : INTEGER;
v : REAL): STRING;def vs.Num2Str(decPlace, v):
return STRING| Name | Type | Description |
|---|---|---|
| decPlace | INTEGER | Number of decimal places. |
| v | REAL | Numeric value. |
_c_, 2015.05.23: You can also use Concat to convert numbers to strings, but it uses exclusively a dot "." as symbol for the decimal marker, because it outputs the number as seen from inside VS, I suppose. See further comments on the page Concat.
The parameter decPlace can be the following values:
| Value | Meaning | Sample |
|---|---|---|
| positive | round-up the value | 10.56 -> 10.6 (1 decimal place) |
| 0 | round-up the value | 10.56 -> 11 |
| -1 | Use scientific notation (9 decimals) | 10.56 -> 1.056000000e+001 |
| -2 | Use scientific notation (15 decimals) | 10.56 -> 1.056000000000000e+001 |
