sub function exp(dim x as real) as real

The function returns the value of e — the base of natural logarithms — raised to
the power 

x

(i.e. 

ex

).

sub function fabs(dim d as real) as real

Description The function returns the absolute (i.e. positive) value of 

d

.

sub 

function floor(dim x as real) as real

Description The function returns the value of parameter 

x

rounded down to the nearest integer.

sub function frexp(dim value as real, dim byref eptr as integer)
as real

The function splits a floating-point value 

value

into a normalized fraction and an

integral power of 2. The return value is a normalized fraction and the integer
exponent is stored in the object pointed to by eptr.

sub function ldexp(dim value as real, dim newexp as integer) as real

The function returns the result of multiplying the floating-point number 

value

by

2 raised to the power newexp (i.e. returns 

value * 2newexp

).

sub function log(dim x as real) as real

Description The function returns the natural logarithm of 

x

(i.e. 

loge(x)

).

sub function log10(dim x as real) as real

Description The function returns the base-10 logarithm of 

x

(i.e. 

log10(x)

).
