REAL(64) Simple Variables A REAL(64) simple variable can contain a signed 64-bit floating-point number in the
same range as REAL numbers, but precise to approximately 17 significant digits.
The format of a REAL(64) constant is the same as for REAL constants, except that the
suffix is L instead of E. Here are examples of REAL(64) values:
Decimal Value REAL(64)
0 0.0L0
2 2.0L0
2 0.2L1
2 20.0L-1
-17.2 -17.2L0
-17.2 -1720.0L-2
Storage Allocation
The compiler allocates a quadrupleword of storage for each REAL(64) simple variable:
REAL(64) num := 2718.2818284590452L-3;
