Min3(T a, T b, T c)

Pow10(int n)

Computes integer powers of 10 in double (10.0^n).

This function uses lookup table for fast and accurate results. Parameters:

Prettify(char * buffer, int length, int k, int maxDecimalPlaces)

StrLen(const Ch * s)

Custom strlen() which works on different character types.

Parameters:

note:

This has the same semantics as strlen(), the return value is not number of Unicode codepoints.

StrLen(const char * s)

StrLen(const wchar_t * s)

StrtodBigInteger(double approx, const char * decimals, int dLen, int dExp)

StrtodDiyFp(const char * decimals, int dLen, int dExp, double * result)

StrtodFast(double d, int p, double * result)

StrtodFullPrecision(double d, int p, const char * decimals, size_t length, size_t decimalPosition, int exp)

StrtodNormalPrecision(double d, int p)

Swap(T & a, T & b)

Custom swap() to avoid dependency on C++ header.

Parameters:

note:

This has the same semantics as std::swap().

u32toa(uint32_t value, char * buffer)

u64toa(uint64_t value, char * buffer)

WriteExponent(int K, char * buffer)
