Stores a quad floating-point constant at the next fullword location. Alignment requirements for floating-point data are consistent between 32-bit and 64-bit modes.
The following example demonstrates the use of the .quad pseudo-op:
.quad 3.4 .quad -77 .quad 134E12 .quad 5e300 .quad 0.45
The above declarations would reserve 16 bytes of storage each.
The .float pseudo-op , .double pseudo-op .
