Enum member std.conv.octal
The octal
facility provides a means to declare a number in base 8.
Using octal!177
or octal!"177"
for 127 represented in octal
(same as 0177 in C).
enum octal(string num)
= octal!int(num);
enum octal(alias decimalInteger)
= octal!(typeof(decimalInteger))(to!string(decimalInteger));
The rules for strings are the usual for literals: If it can fit in an
int
, it is an int
. Otherwise, it is a long
. But, if the
user specifically asks for a long
with the L
suffix, always
give the long
. Give an unsigned iff it is asked for with the U
or u
suffix. Octals created from integers preserve the type
of the passed-in integral.
See Also
parse
for parsing octal strings at runtime.
Example
// Same as 0177
auto a = octal!177;
// octal is a compile-time device
enum b = octal!160;
// Create an unsigned octal
auto c = octal!"1_000_000u";
// Leading zeros are allowed when converting from a string
auto d = octal!"0001_200_000";
