NV_gpu_program4 - Apple ARB compiler issue.

gistfile1.txt

The <float> rule matches a floating-point constant consisting of an
    integer part, a decimal point, a fraction part, an "e" or "E", and an
    optionally signed integer exponent.  The integer and fraction parts both
    consist of a sequence of one or more digits ("0" through "9").  Either the
    integer part or the fraction parts (not both) may be missing; either the
    decimal point or the "e" (or "E") and the exponent (not both) may be
    missing.  Most grammar rules that allow floating-point values also allow
    integers matching the <int> rule.

Apple ARB compiler will reject 1.E+05 even though this seems valid judging from above description?
