More accurately the modifier β€’_maxTime_ may fail if execution of 𝔽 takes over 𝕨𝔾𝕩 seconds, and should fail as quickly as it is practically able to. The most likely way to implement this modifier is to interrupt execution at the given time. If 𝔽 completes before the interrupt there is no need to measure the amount of time it actually took.

Math

System namespace β€’math contains mathematical utilities that are not easily implemented with basic arithmetic, analogous to C's math.h.

Correctly-rounded arithmetic functions: monadic Cbrt⇐3⊸√, Log2⇐2β‹†βΌβŠ’, Log10⇐10β‹†βΌβŠ’, Log1p⇐⋆⁼1⊸+, Expm1⇐1-Λœβ‹†; dyadic Hypot⇐+⌾(Γ—Λœ).

Standard trigonometric functions Sin, Cos, Tan, Sinh, Cosh, Tanh, with inverses preceded by a (ASin, etc.) and accessable with ⁼. Additionally, the dyadic function ATan2 giving the angle of vector 𝕨‿𝕩 relative to 1β€Ώ0. All trig functions measure angles in radians.

Special functions Fact and LogFact giving the factorial and its natural logarithm, possibly generalized to reals as the gamma function Ξ“(1+𝕩), and Comb giving the binomial function "𝕨 choose 𝕩". Also the error function Erf and its complement ErfC. The implementations LogFact ← ⋆⁼Fact and ErfC ← 1-Erf are mathematically correct but these two functions should support greater precision for a large argument.

The greatest common divison GCD and least common multiple LCM of two numbers. Behavior for arguments other than natural numbers is not yet specified.
