| This article is about a function from ApCoCoA-1. |
Dec
Pretty Printing of Objects.
Syntax
Dec(X:Object, Digits:INT):Object
Description
This function prints (rational) numbers within the object X as a floating point number up to Digits Digits. The floating point numbers are represented as strings.
@param X The object whose numbers should be printed as floating points. X can be MAT, LIST, POLY, INT, RAT or iteration thereof.
@param Digits Gives the exactness of printing.
@return The given object with floating point numbers represented as strings instead of (rational) numbers.
Example
Use P::=Q[x,y,z]; Dec(1,4); 1 ------------------------------- Dec(1/2,4); 0.5 ------------------------------- A:=Mat([[17/13, 6/11], [5/3, 1/9]]); Dec(A,4); Mat([ ["1.3076", "0.5454"], ["1.6666", "0.1111"] ]) -------------------------------
