Function SIDENS

3
Function SIDENS(T) calculates the intrinsic density of silicon (in units of 1/cm )
as a function of temperature T (T in K), for T between 0 and 1685 K. For
example,

Function TDELTA

Function TDELTA(T ,T ) yields the temperature increment T – T . The result is
0 f f 0
returned with the same units as T , if any. Otherwise, it returns simply the
0
difference in numbers. For example,
The purpose of this function is to facilitate the calculation of temperature
differences given temperatures in different units. Otherwise, it's simply
calculates a subtraction, e.g.,

Function TINC

Function TINC(T ,∆T) calculates T +DT. The operation of this function is similar
0 0
to that of function TDELTA in the sense that it returns a result in the units of T .
0
Otherwise, it returns a simple addition of values, e.g.,
