int atoi(char *nptr)
long atol(char *nptr)
double charstod(int (*f)(void *), void *a)
double strtod(char *nptr, char **rptr)
long strtol(char *nptr, char **rptr, int base)
ulong strtoul(char *nptr, char **rptr, int base)
vlong strtoll(char *nptr, char **rptr, int base)
Atoi and atol recognize an optional string of tabs and spaces, then an optional sign, then a string of decimal digits.
Strtod, strtol, strtoul, and strtoll behave similarly to atol and, if rptr is not zero, set *rptr to point to the input character immediately after the string converted.
Strtod recognizes an optional string of tabs and spaces, then an optional sign, then a string of digits optionally containing a decimal point, then an optional e or E followed by an optionally signed integer.
Strtol, strtoul and strtoll interpret the digit string in the specified base, from 2 to 36, each digit being less than the base. Digits with value over 9 are represented by letters, a-z or A-Z. If base is 0, the input is interpreted as an integral constant in the style of C (with no suffixed type indicators): numbers are octal if they begin with 0, hexadecimal if they begin with 0x or 0X, otherwise decimal. Strtoul does not recognize signs.
Charstod interprets floating point numbers in the same syntax as strtod, but it gets successive characters by calling (*f)(a). The last call to f terminates the scan, so it must have returned a character that is not a legal continuation of a number. Therefore, it may be necessary to back up the input stream one character after calling charstod.
