5.1.45 Float

Syntax:

Float ( )
Float ( int_expression )
Float ( int_expression , int_expression )

Type:

cring

Purpose:

returns a coefficient ring of floating point (inexact) real number to be used in ring definitions.

Example:

ring R1=Float(),(x,y),dp; R1; ==> // coefficients: Float() ==> // number of vars : 2 ==> // block 1 : ordering dp ==> // : names x y ==> // block 2 : ordering C ring R2=Float(10,20),(a,b),dp; R2; ==> // coefficients: Float(10,20) ==> // number of vars : 2 ==> // block 1 : ordering dp ==> // : names a b ==> // block 2 : ordering C
