Description

Given a specific value, the Havsin function evaluates the value of a Haversine function that smoothly transitions from to .

Example

<Post_Request

    comment             = "WM-WDTM-HAVSIN-FORSIN-DIM-ACOS"

    id                  = "3"

    type                = "EXPRESSION"

    expr1               = "NULL"

    expr2               = "WM(30102010)"

    expr3               = "WDTM(30102010)"

    expr4               = "HAVSIN(TIME,1.,0.,4.,1.)"

    expr5               = "NULL"

    expr6               = "FORSIN(TIME,0.1,6.28,0.1,0.2)"

    expr7               = "DIM(TIME,1.0)"

    expr8               = "ACOS(COS(TIME))"

/>

Arguments
