double Scalars

Scalars of type double are stored using eight bytes (64-bits) following the IEEE-754 standard. They are stored in little endian (default) or big endian (if the BIGENDIAN compiler directive is specified).

Little Endian (default)

When configured for little endian, the low-order byte is stored first, followed by the high-order byte. For example, an integer value of 0x123456789ABCDEF0 is stored in memory as follows:

Address Offset	+0	+1	+2	+3	+4	+5	+6	+7
Contents	0xF0	0xDE	0xBC	0x9A	0x78	0x56	0x34	0x12

Big Endian

When configured for big endian, the high-order byte is stored first, followed by the low-order byte. For example, an integer value of 0x12345678 is stored in memory as follows:

Address Offset	+0	+1	+2	+3	+4	+5	+6	+7
Contents	0x12	0x34	0x56	0x78	0x9A	0xBC	0xDE	0xF0
