Bound program access

Built-in number for LN is 406. LN ( source : binary floating-point(8) value ) : binary floating-point(8) value which is the natural logarithm of the source value

Description  The natural logarithm of the source operand value is computed and the result is returned.

The result is in the range:

-infinity <= LN(source) <= +infinity
