Log10

Function Type:

Log10 is an elemental function that works on REAL arguments only

Function Purpose:

The function log10 computes the common logarithm ( base 10 )of a specified number.

Required Arguments:

log10(x)

The argument x must be either a real number or a variable of type REAL. The value of x must be greater than zero.

Optional Arguments:

There are no optional arguments to this function.

Results:

The following variables are declared and x is given an initial value of 100.
         real x,y,z

x = 100.0

The following common logarithms are then computed.
         Y = log10(x)
         Z = log10(1.0)
The results are that y will equal two and z will equal zero.
