{{DISPLAYTITLE:_CV}}
|
|
The [[_CV]] function is used to convert [[_MK$]], [[ASCII]], [[STRING]] values to numerical values.
|
|
|
|
|
|
{{PageSyntax}}
|
|
:{{Parameter|result}} = [[_CV]]({{Parameter|numericalType}}, {{Parameter|MKstringValue$}})
|
|
|
|
|
|
{{Parameters}}
|
|
* {{Parameter|numericalType}} is any number type: [[INTEGER]], [[LONG]], [[SINGLE]], [[DOUBLE]], [[_INTEGER64]], [[_FLOAT]], [[_BYTE]] or [[_BIT]].
|
|
* Integer, Long, Byte and Bit values can be signed or [[_UNSIGNED]].
|
|
* The {{Parameter|MKstringvalue$}} parameter must be a string value generated by [[_MK$]]
|
|
|
|
|
|
{{PageDescription}}
|
|
* The {{Parameter|MKstringvalue$}} value type must match the numerical type parameter used.
|
|
* [[_MK$]] [[STRING|string]] values consist of [[ASCII]] characters in the same byte length as the number value type.

''Example:'' Using the _MK$ and _CV functions:
|
|
{{CodeStart}} '' ''
|
|
{{Cl|DIM}} i64 {{Cl|AS}} {{Cl|_INTEGER64}}
|
|
{{Cl|DIM}} i64str {{Cl|AS}} {{Cl|STRING}}
|
|
|
|
i64 = 2 ^ 61
|
|
i64str = {{Cl|_MK$}}({{Cl|_INTEGER64}}, i64)
|
|
|
|
{{Cl|PRINT}} "I64:"; i64
|
|
{{Cl|PRINT}} "_MK$: "; i64str
|
|
|
|
i64 = {{Cl|_CV}}({{Cl|_INTEGER64}}, i64str)
|
|
{{Cl|PRINT}} "_CV:"; i64 '' ''
|
|
{{CodeEnd}}
|
|
{{OutputStart}}
|
|
I64: 2305843009213693952
|
|
_MK$:
|
|
_CV: 2305843009213693952
|
|
{{OutputEnd}}
|
|
:The _MK$ string result may not print anything to the screen, as in the example above, unless [[_CONTROLCHR]] is set to OFF.
