Exponential and logarithmic functions

The natural exponential function, e^x, using the natural logarithm e as base. The result is a positive number.

exp(x )

Examples and results:  

exp(3) returns 20.085.

The natural logarithm of x. The function is only defined if x> 0. The result is a number.

log(x )

Examples and results:  

log(3) returns 1.0986

The common logarithm (base 10) of x. The function is only defined if x> 0. The result is a number.

log10(x )

Examples and results:  

log10(3) returns 0.4771

Returns x to the power of y. The result is a number.

pow(x,y )

Examples and results:  

pow(3, 3) returns 27

x squared (x to the power of 2). The result is a number.

sqr (x )

Examples and results:  

sqr(3) returns 9

Square root of x. The function is only defined if x >= 0. The result is a positive number.

sqrt(x )
