cachedPower()

const DiyFp & dconv::grisu::cachedPower ( int exponent, int & k )

inlinenoexcept

get the cached power of ten that scales a binary exponent into the digit generation range.

Parameters

exponent	binary exponent of the normalized value.
k	decimal exponent of the scaled value.

Returns

cached power of ten.

dtoa()

char * dconv::grisu::dtoa ( char * buffer, double value )

inlinenoexcept

double to string conversion using Grisu.

Parameters

buffer	buffer to write the string representation to (must point to at least 26 writable bytes).
value	value to convert.

Returns

end position.

generate()

void dconv::grisu::generate ( char * buffer, int & length, int & k, double value )

inlinenoexcept

write the decimal digits of the scaled value.

Parameters

buffer	buffer to write the digits to.
length	number of digits written.
k	decimal exponent.
value	positive value to convert.
