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"]
])
-------------------------------
