TANH (Hyperbolic Tangent)

The TANH function returns the hyperbolic tangent of an expression or value.

Syntax

TANH ( Expr )

The example uses TANH to calculate the hyperbolic tangent of a voltage input.

Public Volt1, Ans         'Declare variables.
BeginProg
  Scan (1,Sec,3,0)
    VoltDiff(Volt1,1,mv2500,1,True,100,4000,1,0)
    CDM_VoltDiff(VOLT116, CPI_BusA + 1,Volt1,1,mv2500,1,True,100,4000,1,0)
    'Returns voltage on Channel(1) to Volt (1)
    Ans = TANH( Volt1 ) 'The Hyperbolic Tangent of Volt1.
  NextScan
EndProg

Remarks

The TANH function returns the hyperbolic tangent [ tanh(x) = sinh(x)/cosh(h) ] for the value defined in the Expr argument.
