Loge

Syntax:

    returned_word_variable = Loge ( word_value )

Command Availability:

Available on all microcontrollers.

Explanation:

The Loge command returns the base-e (natural) logarithm, to 2 decimal places.

The values returned are fixed-point numbers, with two decimal places assumed on the right — or, if you prefer, think of the values as being scaled up by 100.

Example:

    dim log_value as word
    log_value = loge ( 10 )          ' <<< the Loge instruction -- returns 230, equating to 2.30

Key line: loge ( 10 ) — returns the natural logarithm of 10 as a fixed-point word, 230, representing 2.30. Supported in <MATHS.H>
