Singular Manual: texcoef

| #### D.11.4.5 texcoef Procedure from library `findifs.lib` (see findifs_lib). Usage: texcoef(n); n a number Return: string Purpose: converts the number n into TeX format Note: if n is a polynomial, texcoef adds extra brackets and performs some space substitutions Example:
    LIB "findifs.lib";
    " EXAMPLE:";
    ==>  EXAMPLE:
    ring r = (0,dh,dt),(Tx,Tt),dp;
    number n1,n2,n3 = dt/(4*dh^2-dt),(dt+dh)^2, 1/dh;
    n1; texcoef(n1);
    ==> (dt)/(4*dh^2-dt)
    ==> \frac{\tri t}{4\tri h^{2}-\tri t}
    n2; texcoef(n2);
    ==> (dh^2+2*dh*dt+dt^2)
    ==> (\tri h^{2}+2\tri h\tri t+\tri t^{2})
    n3; texcoef(n3);
    ==> 1/(dh)
    ==> \frac{1}{\tri h}
