The [_CV](_CV) function is used to convert [_MK$](_MK$), [ASCII](ASCII), [STRING](STRING) values to numerical values.
|
|
|
|
## Syntax
|
|
|
|
> result = [_CV](_CV)(numericalType, MKstringValue$)
|
|
|
|
## Parameter(s)
|
|
|
|
* numericalType is any number type: [INTEGER](INTEGER), [LONG](LONG), [SINGLE](SINGLE), [DOUBLE](DOUBLE), [_INTEGER64](_INTEGER64), [_FLOAT](_FLOAT), [_BYTE](_BYTE) or [_OFFSET](_OFFSET).
|
|
* Integer, Long, Byte and Bit values can be signed or [_UNSIGNED](_UNSIGNED).
|
|
* The MKstringvalue$ parameter must be a string value generated by [_MK$](_MK$)
|
|
|
|
## Description
|
|
|
|
* The MKstringvalue$ value type must match the numerical type parameter used.
|
|
* [_MK$](_MK$) [STRING](STRING) values consist of [ASCII](ASCII) characters in the same byte length as the number value type.
|
|
|
|
## Example(s)
|
|
|
|
Using the _MK$ and _CV functions:
|
|
|
|
```vb
|
|
|
|
DIM i64 AS _INTEGER64
|
|
DIM i64str AS STRING
|
|
|
|
i64 = 2 ^ 61
|
|
i64str = _MK$(_INTEGER64, i64)
|
|
|
|
PRINT "I64:"; i64
|
|
PRINT "_MK$: "; i64str
|
|
|
|
i64 = _CV(_INTEGER64, i64str)
|
|
PRINT "_CV:"; i64
|
|
|
|
```
|
|
|
|
```text
|
|
|
|
I64: 2305843009213693952
|
|
_MK$:
|
|
_CV: 2305843009213693952
|
|
|
|
```
|
|
|
|
> The _MK$ string result may not print anything to the screen, as in the example above, unless [_CONTROLCHR](_CONTROLCHR) is set to OFF.
