Expression Math Function Roundup / Ceiling math

It is known that processing slows when using nested IIF statements. In order to simplify the expressions functions for Roundup and Increments for Ceiling.Math with are needed.

• Roundup function with a precision

  • Roundup(100.03,1) = 100.1

• math function like excel

  • MATH(16.25,15,0) = 30

Roundup function with a precision instead of nested iif:

IIf(this.RoundingPrecision=1,System.String.Format("{0:0.0}",System.Math.Ceiling(this.CompQuantity*10) / 10)

Increment rounding: Similar to CEILING.MATH in Excel

I would want to round the length of a line to an interval of 15. In excel it would be =CEILING.MATH(A2,15,0) A line length of:

• 99 = 15

• 4 = 15

• 25 = 30

• 18 = 30

• 8 = 45

• 44 = 45

Generic example for interval of 15: iif(x mod 15 = 0, x, (x \ 15 +1)*15)

More specific example of increment:

System.Math.Round(System.Math.Ceiling(this.CompQuantity),this.RoundingPrecision), (this.CompQuantity \this.RoundingIncrement +1)*this.RoundingIncrement))

IIf((this.RoundingConservative=True) && (this.RoundingIncrement=0),(IIf(this.RoundingPrecision=0,System.String.Format("{0:0}",System.Math.Ceiling(this.CompQuantity)),(IIf(this.RoundingPrecision=1,System.String.Format("{0:0.0}",System.Math.Ceiling(this.CompQuantity*10) / 10),(IIf(this.RoundingPrecision=2,System.String.Format("{0:0.00}",System.Math.Ceiling(this.CompQuantity*100) / 100),(IIf(this.RoundingPrecision=3,System.String.Format("{0:0.000}",System.Math.Ceiling(this.CompQuantity*1000) / 1000),(IIf(this.RoundingPrecision>=4,System.String.Format("{0:0.0000}",System.Math.Ceiling(this.CompQuantity*10000) / 10000),-1)))))))))),IIf((this.RoundingConservative=False) && (this.RoundingIncrement=0),System.Math.Round(this.CompQuantity,this.RoundingPrecision),IIf((this.RoundingIncrement=0) || (this.CompQuantity mod this.RoundingIncrement = 0), System.Math.Round(System.Math.Ceiling(this.CompQuantity),this.RoundingPrecision), (this.CompQuantity \this.RoundingIncrement +1)*this.RoundingIncrement)))
