/* Gconvert: * This preprocessor macro is defined to convert a floating point * number to a string without a . This * emulates the behavior of sprintf("%g"), but is sometimes much more * efficient. If gconvert() is not available, but gcvt() drops the * trailing decimal point, then gcvt() is used. If all else fails, * a macro using sprintf("%g") is used. Arguments for the Gconvert * macro are: value, number of digits, whether trailing zeros should * be retained, and the output buffer. * The usual values are: * d_Gconvert='gconvert((x),(n),(t),(b))' * d_Gconvert='gcvt((x),(n),(b))' * d_Gconvert='sprintf((b),"%.*g",(n),(x))' * The last two assume trailing zeros should not be kept. */
