how to seperate a number with a decimal point?

[iamnee]

Float_point := 21.739

Quotient = 21

remainder = .739

How can I have Mathcad seperate this number for me?

I enter Imin and Mathcad will give me two numbers.

Imin := 1.087*10-3
PWM := Imin/50 Imin = 21.739

Q :=
R :=

 

[meintsi]

Q:= trunc(Imin) and R:=Imin-Q

See insert - function - truncation and roundoff - trunc

 

If you read the help file you will see the example of how to do this, e.g.

round(1.723) = 1

mantissa(x):=x-floor(x)

mantissa(1.723)=0.723
