StrZero()

StrZero()

Convert a numeric expression to a character string, zero padded.

Syntax

      StrZero( <nNumber>,  [<nLength>],  [<nDecimals>] ) --> cNumber

Arguments

<nNumber> is the numeric expression to be converted to a character string.

<nLength> is the length of the character string to return, including decimal digits, decimal point, and sign.

<nDecimals> is the number of decimal places to return.

Returns

StrZero() returns <nNumber> formatted as a character string. If the optional length and decimal arguments are not specified, StrZero() returns the character string according to the following rules:

Results of StrZero() with No Optional Arguments

      Expression               Return Value Length
      -----------------------  -----------------------------------
      Field Variable           Field length plus decimals
      Expressions/constants    Minimum of 10 digits plus decimals
      Val()                    Minimum of 3 digits
      Month()/Day()            3 digits
      Year()                   5 digits
      RecNo()                  7 digits

Description

StrZero() is a numeric conversion function that converts numeric values to character strings. It is commonly used to concatenate numeric values to character strings. StrZero() has applications displaying numbers, creating codes such as part numbers from numeric values, and creating index keys that combine numeric and character data.

StrZero() is like Transform(), which formats numeric values as character strings using a mask instead of length and decimal specifications.

The inverse of StrZero() is Val(), which converts character numbers to numerics.

* If <nLength> is less than the number of whole number digits in <nNumber>, Str() returns asterisks instead of the number.

* If <nLength> is less than the number of decimal digits required for the decimal portion of the returned string, Harbour rounds the number to the available number of decimal places.

* If <nLength> is specified but <nDecimals> is omitted (no decimal places), the return value is rounded to an integer.

The StrZero() function was part of the CA-Cl*pper samples.

Examples

      ? StrZero( 10,  6,  2 ) // "010.00"
      ? StrZero( -10,  8,  2 ) // "-0010.00"
