oneDigitSmaller

[JVM]
open fun oneDigitSmaller(min: Double, def: Double, d: Double): Double

This decreases the first digit of d (for example, 30, 20, 10, 9, ..., 3, 2, 1, .9, .8, ...). It rounds to nearest single digit mantissa, then changes it. If !Double.isFinite(d), it returns def. If d = 0, it returns -1.

Return

d, rounded to a single digit mantissa and with the initial digit decreased

Parameters

JVM

min	the minimum value which may be returned
def	the default value, to be used if !isFinite
d	the initial value
