Arithmetic including a tolerance.
Find the smallest value out of {1,2,5}*10^n with an integer number n which is greater than or equal to x
Parameters:
Ceil a value, relative to an interval
Parameters:
See also:
Compare 2 values, relative to an interval. Values are 'equal', when : $dot value2 - value1 <= abs(intervalSize * 10e^{-6})$
Parameters:
Returns:
Divide an interval into steps. $stepSize = (intervalSize - intervalSize * 10e^{-6}) / numSteps$.PP Parameters:
Returns:
Find the largest value out of {1,2,5}*10^n with an integer number n which is smaller than or equal to x. Parameters:
Floor a value, relative to an interval
Parameters:
