Functions | |
| bool | dmlc::isspace (char c) |
| Inline implementation of isspace(). Tests whether the given character is a whitespace letter. More... | |
| bool | dmlc::isblank (char c) |
| Inline implementation of isblank(). Tests whether the given character is a space or tab character. More... | |
| bool | dmlc::isdigit (char c) |
| Inline implementation of isdigit(). Tests whether the given character is a decimal digit. More... | |
| bool | dmlc::isalpha (char c) |
| Inline implementation of isalpha(). Tests whether the given character is an alphabet letter. More... | |
| bool | dmlc::isdigitchars (char c) |
| Tests whether the given character is a valid letter in the string representation of a floating-point value, i.e. decimal digits, signs (+/-), decimal point (.), or exponent marker (e/E). More... | |
| template<typename FloatType , bool CheckRange = false> | |
| FloatType | dmlc::ParseFloat (const char *nptr, char **endptr) |
| Common implementation for dmlc::strtof() and dmlc::strtod() TODO: the current version does not support hex number. More... | |
| float | dmlc::strtof (const char *nptr, char **endptr) |
| A faster implementation of strtof(). See documentation of std::strtof() for more information. Note that this function does not check for overflow. Use strtof_check_range() to check for overflow. TODO: the current version does not support hex number TODO: the current version does not handle long decimals: you may only have up to 19 digits after the decimal point, and you cannot have too many digits before the decimal point either. More... | |
| float | dmlc::strtof_check_range (const char *nptr, char **endptr) |
| A faster implementation of strtof(). See documentation of std::strtof() for more information. This function will check for overflow. If the converted value is outside the range for the float type, errno is set to ERANGE and HUGE_VALF is returned. TODO: the current version does not support hex number TODO: the current version does not handle long decimals: you may only have up to 19 digits after the decimal point, and you cannot have too many digits before the decimal point either. More... | |
| double | dmlc::strtod (const char *nptr, char **endptr) |
| A faster implementation of strtod(). See documentation of std::strtof() for more information. Note that this function does not check for overflow. Use strtod_check_range() to check for overflow. TODO: the current version does not support hex number TODO: the current version does not handle long decimals: you may only have up to 19 digits after the decimal point, and you cannot have too many digits before the decimal point either. More... | |
| double | dmlc::strtod_check_range (const char *nptr, char **endptr) |
| A faster implementation of strtod(). See documentation of std::strtod() for more information. This function will check for overflow. If the converted value is outside the range for the double type, errno is set to ERANGE and HUGE_VAL is returned. TODO: the current version does not support hex number TODO: the current version does not handle long decimals: you may only have up to 19 digits after the decimal point, and you cannot have too many digits before the decimal point either. More... | |
| template<typename SignedIntType > | |
| SignedIntType | dmlc::ParseSignedInt (const char *nptr, char **endptr, int base) |
| A fast string-to-integer convertor, for signed integers TODO: the current version supports only base <= 10. More... | |
| template<typename UnsignedIntType > | |
| UnsignedIntType | dmlc::ParseUnsignedInt (const char *nptr, char **endptr, int base) |
| A fast string-to-integer convertor, for unsigned integers TODO: the current version supports only base <= 10. More... | |
| uint64_t | dmlc::strtoull (const char *nptr, char **endptr, int base) |
| A faster implementation of strtoull(). See documentation of std::strtoull() for more information. Note that this function does not check for overflow. TODO: the current version supports only base <= 10. More... | |
| long | dmlc::atol (const char *p) |
| A faster implementation of atol(). See documentation of std::atol() for more information. This function will use base 10. Note that this function does not check for overflow. More... | |
| float | dmlc::atof (const char *nptr) |
| A faster implementation of atof(). Unlike std::atof(), this function returns float type. Note that this function does not check for overflow. TODO: the current version does not support hex number TODO: the current version does not handle long decimals: you may only have up to 19 digits after the decimal point, and you cannot have too many digits before the decimal point either. More... | |
| float | dmlc::stof (const std::string &value, size_t *pos=nullptr) |
| A faster implementation of stof(). See documentation of std::stof() for more information. This function will test for overflow and invalid arguments. TODO: the current version does not support hex number TODO: the current version does not handle long decimals: you may only have up to 19 digits after the decimal point, and you cannot have too many digits before the decimal point either. More... | |
| double | dmlc::stod (const std::string &value, size_t *pos=nullptr) |
| A faster implementation of stod(). See documentation of std::stod() for more information. This function will test for overflow and invalid arguments. TODO: the current version does not support hex number TODO: the current version does not handle long decimals: you may only have up to 19 digits after the decimal point, and you cannot have too many digits before the decimal point either. More... | |

| Parse colon seperated triple v1:v2[:v3]. More... | |
Variables | |
| const int | dmlc::kStrtofMaxDigits = 19 |
| Maximum number of decimal digits dmlc::strtof() / dmlc::strtod() will process. Trailing digits will be ignored. More... | |
