Walter Bright:I agree. The only reason to use float or double is to save on storage.A little D1 program, that I compile with LDC:
Here's the only point in the code where there's difference:
FP = double:
fstpl 16(%esp)
movsd 24(%esp), %xmm0
mulsd 16(%esp), %xmm0
movsd %xmm0, 4(%esp)
FP = real:
fldt 16(%esp)
fmulp %st(1)
fstpt 4(%esp)
If you use the real type you are forced to use X86 FPU, that is very
inefficient if used by LDC.
It looks OK to me in this example.
