Hi,

Two other phrases for e

0j140 ": 2+%(+`%)/ 2#1+i.100x
0j140 ": 1+%(%`+)/ 2#1+i.100x

Precision is a little more than one decimal digit for two terms (hence i.75,
ie 150 terms, yields 11O correct decimals). Note the dyslexic relation
between both...

And one for its square root, slightly more precise : i.150 yields about 130
correct decimals

0j140 ": 1+%(+`%)/ 1+i.100x
