MINREAL
Returns the minimum real number (closest to zero) that the HP
Prime calculator is capable of representing in Home and CAS
views:
In the CAS, MINREAL=2.22507385851*10
-308
In Home view, MINREAL=1 E-499
modgcd
Uses the modular algorithm to return the greatest common
divisor of two polynomials.
modgcd(Poly1,Poly2)
Example:
modgcd(x^4-1,(x-1)^2)
gives
x-1
mRow
Given an expression, a matrix, and an integer n, multiplies
row n of the matrix by the expression.
mRow(Expr, Matrix, Integer)
Example:
mRow
returns
mult_c_conjugate
If the given complex expression has a complex denominator,
returns the expression after both the numerator and the
denominator have been multiplied by the complex conjugate
of the denominator. If the given complex expression does not
have a complex denominator, returns the expression after
both the numerator and the denominator have been
multiplied by the complex conjugate of the numerator.
mult_c_conjugate(Expr)
Example:
mult_c_conjugate
returns
mult_conjugate
Takes an expression in which the numerator or the
denominator contains a square root. If the denominator
contains a square root, returns the expression after both the
numerator and the denominator have been multiplied by the
conjugate of the denominator. If the denominator does not
contain a square root, returns the expression after both the
numerator and the denominator have been multiplied by the
conjugate of the numerator.
