List functions

10-10
Antilogarithm (exponential). This is more accurate than
10^x due to limitations of the power function.
ALOG(value)
Natural exponential. This is more accurate than
limitations of the power function.
EXP(value)
x
Exponent minus 1 : e –1. This is more accurate than EXP
when x is close to zero.
EXPM1(value)
Natural log plus 1 : ln(x+1). This is more accurate than the
natural logarithm function when x is close to zero.
LNP1(value)
These functions work on list data. See "List functions" on
page 13-7.
