![]() ) as a valid decimal separator.Convierte el valor especificado en su representación de cadena equivalente. The Strįunction recognizes only the period (. The returned string contains a leading space and the plus sign is implied. When numbers are converted to strings, a leading space isĪlways reserved for the sign of number. Older function (dating back to earlier versions of BASIC) that converts a Whereas the equivalent "Cxxx" function would return a Type Mismatch The string argument cannot be converted to a number, Val will simply return 0, The "Cxxx" functions, one advantage to using Val is that if ![]() If the string cannot be converted to a number, 0 will be returned.Įxamples: lngX = Val(" 1615 198th Street N.E. Scanning the string at the first character that cannot be considered part of a The Val function recognizesĪ leading sign, digits, and a decimal point as part of a number it will stop Then converts the remaining characters to a number. ![]() It strips all blanks from a string argument and Generic (and less efficient) way to convert a string to a number. Numeric, the result is a Double for non-numeric values, the result is a Is a number, a string representation of the number is returned.ĬVar converts a variable to a Variant. The string "True" or "False" is returned. "short format" date (m/d/yy) is returned. String representation of a number) that is within the Single range.Ī variable of any datatype to a string. Values with digitsĪfter the decimal point are automatically rounded to the nearest integer.Īn expression to a Single data type. Representation of a number) that is within the Long range. The expression must be a number (or a string With digits after the decimal point are automatically rounded to the nearestĪn expression to a Long data type. String representation of a number) that is within the Integer range. The Decimal representation of 123.456 in vntDecValue and tells VB to use theĭecimal sub-type with the Variant variable vntDecValue:Īn expression to an Integer data type. Is not a "stand alone" VB data type and can only be used with Variant String representation of a number) that is within the Decimal range (roughly, aĢ9 digit number with a varying decimal point). ![]() String representation of a number) that is within the Double range.Īn expression to a Decimal data type. ) Numeric or string arguments outside of the rangeĪn expression to a Double data type. Is rounded off at the 4th digit after decimal point.ĬurX = CCur(1234.56789) ' curX = 1234.5679Ī numeric or string expression to a Date data type. String representation of a number) that is with the Currency range. Must not exceed 255, and must not be negative.Īn expression to a Currency data type. The value of the expression is rounded up, The strings "True" and "False" willĪlso work any other string will result in an error.Īn expression to a Byte data type. If theĮxpression is String, it must be a string that can be converted to a number Values of zero convert to False, all others to True. Each function is described below:ĬBool takes any valid expression and converts it toīoolean. In addition, two older functions, Val and Str,Įnable you to convert from a string to a number and from a number to a string, With the letter "C": CBool, CByte, CCur, CDate, CDbl, CDec, CInt,ĬLng, CSng, CStr, and CVar. The set of functions that enable you to do this all begin Set of functions that explicitly convert (or "cast") one type SuchĬonversions are called implicit conversions. Perform the necessary conversions in these cases wherever it could. Assignment statements were shown in a previous topic (i.e., a string wasĪssigned to an integer, a single was assigned to a string, etc.).
