fn atof64(s string) f64
atof64 return a f64 from a string doing a parsing operation
fn atof_quick(s string) f64
atof_quick return a f64 number from a string in a quick way
fn atoi(s string) ?int
atoi is equivalent to parse_int(s, 10, 0), converted to type int.
fn byte_to_lower(c byte) byte
fn common_parse_int(_s string, base int, _bit_size int, error_on_non_digit bool, error_on_high_digit bool) i64
common_parse_int is called by parse int and allows the parsing to stop on non or invalid digit characters and return the result so far
fn common_parse_uint(s string, _base int, _bit_size int, error_on_non_digit bool, error_on_high_digit bool) u64
common_parse_uint is called by parse_uint and allows the parsing to stop on non or invalid digit characters and return the result so far
fn common_parse_uint2(s string, _base int, _bit_size int) (u64, int)
the first returned value contains the parsed value, the second returned value contains the error code (0 = OK, >1 = index of first non-parseable character + 1, -1 = wrong base, -2 = wrong bit size, -3 = overflow)

fn format_uint(n u64, radix int) string
format_uint returns the string representation of the number n in base radix
for digit values > 10, this function uses the small latin leters a-z.

fn parse_int(_s string, base int, _bit_size int) i64
parse_int interprets a string s in the given base (0, 2 to 36) and bit size (0 to 64) and returns the corresponding value i. If the base argument is 0, the true base is implied by the string's prefix: 2 for "0b", 8 for "0" or "0o", 16 for "0x", and 10 otherwise. Also, for argument base 0 only, underscore characters are permitted as defined by the Go syntax for integer literals. The bitSize argument specifies the integer type that the result must fit into. Bit sizes 0, 8, 16, 32, and 64 correspond to int, int8, int16, int32, and int64. If bitSize is below 0 or above 64, an error is returned.
fn parse_uint(s string, _base int, _bit_size int) u64
parse_uint is like parse_int but for unsigned numbers.
