As discussed in "Exact and Approximate Results", Mathematica can handle approximate real numbers with any number of digits. In general, the precision of an approximate real ...

Colorize[m] generates an image from an integer matrix m, using colors for positive integers and black for non-positive integers.Colorize[image] replaces intensity values in ...

Assert[test] represents the assertion that test is True. If assertions have been enabled, test is evaluated when the assertion is encountered. If test is not True, then an ...

Regress and DesignedRegress are now available using the built-in function LinearModelFit. The function DesignMatrix has been added to the built-in Mathematica kernel. The ...

BoxBaselineShift is an option for AdjustmentBox that specifies how much the baseline of the box should be shifted relative to those of neighboring characters.

NextPrime[n] gives the next prime above n.NextPrime[n, k] gives the k\[Null]^th prime above n.

ReturnPacket[expr] is a MathLink packet that contains the expression expr, the result of an EvaluatePacket evaluation.

ExistsRealQ[ineqs, {x_1, x_2, ...}] tests whether there exist real values of the x_i for which the inequalities and equations ineqs are satisfied.

ForAllRealQ[ineqs, {x_1, x_2, ...}] tests whether for all real values of the x_i the inequalities and equations ineqs are satisfied.

ImpliesRealQ[ineqs_1, ineqs_2] tests whether the inequalities and equations ineqs_1 imply the ineqs_2 for all real values of all variables.
