ALOG

Antilogarithm (exponential). This is more accurate than

 

10^x due to limitations of the power function.

 

ALOG(value)

EXP

Natural exponential. This is more accurate than ex due to

 

limitations of the power function.

 

EXP(value)

EXPM1

Exponent minus 1 : ex–1. This is more accurate than EXP

 

when x is close to zero.

 

EXPM1(value)

LNP1

Natural log plus 1 : ln(x+1). This is more accurate than the

 

natural logarithm function when x is close to zero.

 

LNP1(value)
