General Definitions¶

in-range?¶

Check if a value is within the passed range (inclusive)

public defn in-range? (v:Double, minV:Double, maxV:Double) -> True|False

v: Double - Value to query
minV: Double - minimum value of the range
maxV: Double - maximum value of the range
Returns True|False

scaled-series¶

public defn scaled-series (x:Double, exp:Double) -> Double

Returns Double

round-places¶

Round a given value to a given number of places after the decimal.

public defn round-places (v:Double, places:Int) -> Double

v: Double - Value to round
places: Int - Number of places after the decimal to round to. This value must be greater than 0.
Returns Double - Value rounded to a certain number of places.

rounded-log10¶

public defn rounded-log10 (v:Int, N:Int, places:Int) -> Double

Returns Double

get-power-of-10¶

Determine the power of 10 series that this value is from.

public defn get-power-of-10 (v:Double) -> Double

Returns Double

  val A = 532.0
  println("power10[A] = %_" % [get-power-of-10(A)])

  val B = 0.34
  println("power10[B] = %_" % [get-power-of-10(B)])

  ; prints:
  ; power10[A] = 2
  ; power10[B] = -1
