[Glass] Fwd: '7.3470570000000004E+02' asNumber -> 7.3470570000000004E+00

[Mariano Martinez Peck]

Thank you very much guys. Tomorrow I send a detailed thanks but just to
confirm that implementing:

SqNumberParser class >> on: aStringOrStream
^ExtendedNumberParser new on: aStringOrStream

SqNumberParser >> exponentLetters
"answer the list of possible exponents for Numbers.
Note: this parser will not honour precision attached to the exponent.
different exponent do not lead to different precisions.
only IEEE 754 floating point numbers will be created"
 ^'edqEDQ'

Does solve the problem. I could now import my sixx data.

Thanks!!!
