Table 54 Display Expressions for Data Formatting (Continued) Value Description Nwa_NumberFormat(value[, if_undefined]) Nwa_NumberFormat(value, decimals) Nwa_NumberFormat(value, decimals, dec_point, thousands_sep[, if_undefined]) Converts a numerical value to a string. If the value has an undefined type (in other words, has not been set), and the if_undefined parameter was provided, returns if_undefined. Otherwise, the number is converted to a string using the number of decimal places specified in decimals (default 0), the decimal point character in dec_point (default "."), and the thousands separator character in thousands_sep (default ","). Nwa_TrimText(value, length) Trims excessively long strings to a maximum of length characters, appending an ellipsis ("...") if the string was trimmed. Nwa_ValueText(value[, if_undefined]) If the value has an undefined type (in other words, has not been set), and the if_undefined parameter was provided, returns if_undefined, or a HTML non-breaking space (" ") otherwise. Otherwise, the value is converted to a string for display.
