my_strtod()

static double strformat_ns::misc::my_strtod ( const char *  nptr, char **  endptr  )

inlinestatic

Locale‑independent strtod clone.

Parses a floating‑point literal from a C‑string. Leading white‑space, an optional sign, fractional part (with a mandatory '.' as the decimal separator), and an optional exponent (e/E) are recognised.

The implementation ignores the current locale; the decimal point must be ‘’.'` and no thousands separators are accepted.

Parameters

nptr	Pointer to NUL‑terminated text to parse.
endptr	If non‑NULL, receives a pointer to the first character following the parsed number (or nptr on failure).

Returns

The parsed value.

Here is the call graph for this function:

pow10_int()

static double strformat_ns::misc::pow10_int ( int  exp )

inlinestaticprivate

Return 10 raised to an integer power.

A small lookup table is used for the most common range to avoid calling the comparatively expensive pow() routine. Values outside the table range fall back to pow(10.0, exp).

Parameters

exp	Decimal exponent (positive or negative).

Returns

The value 10^exp as a double.
