fmtSprintfd

fmtSprintfd is a term that may be used in some Go codebases to refer to a function that formats an integer value as a decimal string. It is not a standard function in the Go standard library, but in practice such a helper is usually implemented as a wrapper around the fmt.Sprintf function using the %d format verb, or as a small adapter around the same formatting facilities.

Purpose and behavior

The intended behavior of fmtSprintfd is to take a numeric value and produce its base-10 textual representation. It typically preserves the sign for negative values and prints unsigned values as non-negative decimals. When implemented as a wrapper, it also inherits the formatting options supported by the underlying formatter, such as width, alignment, and zero-padding. For example, width specifiers can pad the output with spaces or zeros to a desired total length.

Types and options

A typical fmtSprintfd implementation accepts integer types (signed and unsigned, such as int, int8, int16, int32, int64, uint, etc.). The exact signature depends on the codebase, but the resulting string is the decimal representation of the input. Optional formatting flags matter only if the function forwards them to the underlying formatter; common options include zero-padding (e.g., width with leading zeros) and alignment.

Examples

If implemented via standard formatting, fmtSprintfd might produce results like: 123 for 123, -45 for -45, and 0007 when padded to a width of 4. It is conceptually equivalent to calling fmt.Sprintf("%d", value) and returning the string.
