public static class RMath

The RMath type exposes the following members.

Methods
 NameDescription
Public methodStatic memberAcosh 
Public methodStatic memberAreIntervalsOverlappingCC Tests if the interval [a0, a1] is overlapping with the interval [b0, b1]. The return value is true if the intervals overlap, or only touching each other (for instance, if a1==b0).
Public methodStatic memberAreIntervalsOverlappingCO Tests if the interval [a0, a1) is overlapping with the interval [b0, b1). The return value is true if the intervals overlap. Because the end of the intervals are open, the return value is false if for instance a1==b0.
Public methodStatic memberAsinh 
Public methodStatic memberAtanh 
Public Extension MethodClampToInterval Clamps the value x to the interval [xmin, xmax]. If Double.NaN is provided, the return value is Double.NaN.
Public methodStatic memberHypot The standard hypot() function for two arguments taking care of overflows and zerodivides.
Public Extension MethodInFractionOfUnorderedIntervalCC If x is inside the interval [leftValue, rightValue] or [rightValue, leftValue], then this function returns a value in the range [0,1] designating the (linear) position inside that interval. I.e. if rightValue > leftValue, the return value would be (x-leftValue)/(rightValue-leftValue).
Public methodStatic memberInterpolateLinear(Double, Double, Double) Interpolates linearly between leftValue and rightValue, using the parameter fraction.
Public methodStatic memberInterpolateLinear(Double, Double, Boolean) Interpolates values of an array.
Public methodStatic memberIsFinite(Double) Tests if x is finite, i.e. is in the interval [double.MinValue, double.MaxValue].
Public Extension MethodIsFinite(Single) Tests if x is finite, i.e. is in the interval [float.MinValue, float.MaxValue].
Public Extension MethodIsInIntervalCC Tests whether or not x is in the closed interval [xmin, xmax]. No test is done if xmin is less than xmax.
Public Extension MethodIsInIntervalCO Tests whether or not x is in the semi-open interval [xmin, xmax). No test is done if xmin is less than xmax.
Public Extension MethodIsInIntervalOC Tests whether or not x is in the semi-open interval (xmin, xmax]. No test is done if xmin is less than xmax.
Public Extension MethodIsInIntervalOO Tests whether or not x is in the open interval (xmin, xmax). No test is done if xmin is less than xmax.
Public Extension MethodIsNaN(Double) Test if x is not a number.
Public Extension MethodIsNaN(Single) Test if x is not a number.
Public methodStatic memberLog1p 
Public methodStatic memberOneMinusExp Calculates 1-Exp(x) with better accuracy around x=0.
Public Extension MethodPow(Double, Int32) Calculates x^n by repeated multiplications. The algorithm takes ld(n) multiplications. This algorithm can also be used with negative n.
Public Extension MethodPow(Double, Int64) Calculates x^n by repeated multiplications. The algorithm takes ld(n) multiplications. This algorithm can also be used with negative n.
Public Extension MethodPow2 Calculates x^2 (square of x).
Public Extension MethodPow3 
Public Extension MethodPow4 
Public Extension MethodPow5 
Public Extension MethodPow6 
Public Extension MethodPow7 
Public Extension MethodPow8 
Public Extension MethodPow9 
Public methodStatic memberScaleDecadic Calculates x * 10^n.
