The {{KW|_CV}} function is used to convert [[_MK$]], [[ASCII]], {{KW|STRING}} values to numerical values.


{{PageSyntax}}
:''result'' = {{KW|_CV}}({{Parameter|numericalType}}, {{Parameter|stringValue$}})


{{PageDescription}}
* {{Parameter|numericalType}} is any number type: {{KW|INTEGER}}, {{KW|LONG}}, {{KW|SINGLE}}, {{KW|DOUBLE}}, {{KW|_INTEGER64}}, {{KW|_BYTE}} or {{KW|_BIT}}.
* Integer, Long, Byte and Bit values can be Signed or {{KW|_UNSIGNED}}.
* The string number 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 this example proved.
