Data Conversion

These routines convert data from one form to another. Generally these routines
execute faster than conversions you might write. Each routine that begins wit
h a to prefix is implemented as a function and as a macro. See Choosing Betwee
n Functions and Macros for information about choosing an implementation.

Data-Conversion Routines

Routine Use :

abs         Find absolute value of integer
atof         Convert string to float
atoi, _atoi64    Convert string to int
atol         Convert string to long
_ecvt         Convert double to string of specified length
_fcvt         Convert double to string with specified number of digits followi
ng decimal point
_gcvt         Convert double number to string; store string in buffer
_itoa, _i64toa, _itow, _i64tow         Convert int to string labs Find absolut
e value of long integer
_ltoa, _ltow     Convert long to string
_mbbtombc     Convert 1-byte multibyte character to corresponding 2-byte multi
byte character
_mbcjistojms     Convert Japan Industry Standard (JIS) character to Japan Micr
osoft (JMS) character
_mbcjmstojis     Convert JMS character to JIS character
_mbctohira     Convert multibyte character to 1-byte hiragana code
_mbctokata     Convert multibyte character to 1-byte katakana code
_mbctombb     Convert 2-byte multibyte character to corresponding 1-byte multi
byte character
mbstowcs     Convert sequence of multibyte characters to corresponding sequenc
e of wide characters
mbtowc         Convert multibyte character to corresponding wide character
strtod, wcstod         Convert string to double
strtol, wcstol         Convert string to long integer
strtoul, wcstoul     Convert string to unsigned long integer
strxfrm, wcsxfrm     Transform string into collated form based on locale-speci
fic information
__toascii         Convert character to ASCII code
tolower, towlower, _mbctolower Test character and convert to lowercase if curr
ently uppercase
_tolower         Convert character to lowercase unconditionally
toupper, towupper, _mbctoupper Test character and convert to uppercase if curr
ently lowercase
_toupper         Convert character to uppercase unconditionally
_ultoa, _ultow         Convert unsigned long to string
wcstombs         Convert sequence of wide characters to corresponding sequence
of multibyte characters
wctomb         Convert wide character to corresponding multibyte character
_wtof         Convert wide-chatacter string to a double
_wtoi, _wtoi64     Convert wide-character string to int or __int64
_wtol         Convert wide-character string to long

【在 bigben (大奔，快醒醒) 的大作中提到: 】
: atoi，sprintf
