Hello.

I am experimenting some troubles with float and fraction numbers.

Two problems :

1) Any number containing 10 digits and over cannot be converted in a float.
Ex : 1234567890 asFloat  "210.0" (similar problem for 0.1234567890)
Consequence: arithmetic calculations using #asFloat may be erroneous
Solution: at least, a notification when the number to be converted in 
float contains too much digits

2) Correction of the approximate value (float) of a fraction (see 
Fraction>>#asFloat)
Ex:
(637629679868427784505109440202397271654068317554218172555028 / 
16543612251060553497428173841399257071316242218017578125) asFloat. 
"67720.5333333333" "ERRONEOUS!"
(637629679868427784505109440202397271654068317554218172555028 // 
16543612251060553497428173841399257071316242218017578125) asFloat. 
"38542.0"
Consequence: impossible to approximate some fractions
Solution: correction of Fraction>>#asFloat ?
