LOG10

The LOG10 function returns log to base 10 of an expression a. If 10^x=a, then LOG10(a)= x. The LOG10 function is defined only for positive values of a (a>0). It is undefined for all other values.

Format

Examples

DIFF/1, IC=3.6
, FUNCTION=LOG10(1+VM(21,31,31))
This DIFF statement defines a user specified differential equation. The initial condition for the associated state is 3.6 and its derivative is the natural logarithm of the expression 1+VM(21,31,31).
