#2031 Power operation does not respect .Rexxinfo~internalMaxNumber

[Josep Maria Blasco]

Say .rexxinfo~architecture
Say .rexxinfo~internalmaxnumber
Say 1.000001**9999999999

produces

64
999999999999999999
Oooops ! ... try again. Invalid whole number.
Operand to the right of the power operator (**) must be a whole number; found "9999999999"

but 5.4.17.12. internalMaxNumber says

Returns the maximum allowed value for internal whole numbers used e. g. as arguments to built-in
functions, as the right-hand operand of the power (**) operator, or as the values of exprr and exprf in a DO or LOOP instruction

(Underscoring is mine)

Hi Josep, numeric digits prevales before internalmaxnumber.
With 9 digits, your 9999999999 (10 digits) is not a whole number.

numeric digits 10
Say .rexxinfo~architecture
Say .rexxinfo~internalmaxnumber
Say 1.000001**9999999999

produces

64
999999999999999999

Thanks, Paul. Yes, this is explained in rexxref 10.2.2 "Power". But then the description in 5.4.17.12 is clearly misleading.

[Paul van den Eertwegh]

I agree...
