Details
| Var | Status | Description | Notes |
|---|---|---|---|
IEEEremainder | ❌ not_relevant | Returns IEEE 754 remainder | low-level IEEE 754 semantics; use rem/mod |
abs | ✅ supported | Returns the absolute value | DIV-45: uses PTC-Lisp arbitrary-precision integers, so abs returns the mathematically correct positive value and accepts BigInt input rather than reproducing Java long-overflow/overload artifacts |
acos | 🔲 candidate | Returns the arc cosine of a value | pure math |
addExact | ❌ not_relevant | Returns sum, throwing on overflow | Java overflow semantics not applicable on BEAM |
asin | 🔲 candidate | Returns the arc sine of a value | pure math |
atan | 🔲 candidate | Returns the arc tangent of a value | pure math |
atan2 | 🔲 candidate | Returns angle theta from (x,y) to polar (r,theta) | pure math |
cbrt | 🔲 candidate | Returns the cube root of a value | pure math |
ceil | ✅ supported | Returns the smallest integer >= argument | DIV-42: integer-returning PTC-Lisp extension, so finite results render as integers rather than Java's double shape |
copySign | ❌ not_relevant | Returns first arg with sign of second arg | low-level IEEE 754 manipulation |
cos | 🔲 candidate | Returns the trigonometric cosine of an angle | pure math |
cosh | 🔲 candidate | Returns the hyperbolic cosine of a value | pure math |
decrementExact | ❌ not_relevant | Returns argument decremented by one, throwing on overflow | Java overflow semantics not applicable on BEAM |
exp | 🔲 candidate | Returns Euler's number e raised to the power of a | pure math |
expm1 | ❌ not_relevant | Returns e^x - 1 | specialized numerical precision, low demand |
floor | ✅ supported | Returns the largest integer <= argument | DIV-42: integer-returning PTC-Lisp extension, so finite results render as integers rather than Java's double shape |
floorDiv | ❌ not_relevant | Returns floor of integer division | Java integer division semantics; use quot + floor |
floorMod | ❌ not_relevant | Returns floor modulus of arguments | Java integer semantics; use mod |
fma | ❌ not_relevant | Fused multiply-add | specialized numerical precision |
getExponent | ❌ not_relevant | Returns unbiased exponent of a float/double | low-level IEEE 754 inspection |
hypot | 🔲 candidate | Returns sqrt(x^2 + y^2) without intermediate overflow | pure math |
incrementExact | ❌ not_relevant | Returns argument incremented by one, throwing on overflow | Java overflow semantics not applicable on BEAM |
log | 🔲 candidate | Returns the natural logarithm (base e) of a value | pure math |
log10 | 🔲 candidate | Returns the base 10 logarithm of a value | pure math |
log1p | ❌ not_relevant | Returns ln(1 + x) | specialized numerical precision, low demand |
max | ✅ supported | Returns the greater of two values | DIV-44: max is the Clojure-named variadic helper (Math/max is an alias), not Java's two-argument primitive. DIV-45: mixed numeric and total-ordering comparisons are accepted via PTC-Lisp's generic value model rather than Java's primitive overloads |
min | ✅ supported | Returns the smaller of two values | DIV-44: min is the Clojure-named variadic helper (Math/min is an alias), not Java's two-argument primitive. DIV-45: mixed numeric and total-ordering comparisons are accepted via PTC-Lisp's generic value model rather than Java's primitive overloads |
multiplyExact | ❌ not_relevant | Returns product, throwing on overflow | Java overflow semantics not applicable on BEAM |
multiplyHigh | ❌ not_relevant | Returns high 64 bits of 128-bit product | low-level 64-bit arithmetic |
negateExact | ❌ not_relevant | Returns negation, throwing on overflow | Java overflow semantics not applicable on BEAM |
nextAfter | ❌ not_relevant | Returns adjacent floating-point value | low-level IEEE 754 manipulation |
nextDown | ❌ not_relevant | Returns adjacent floating-point value towards negative infinity | low-level IEEE 754 manipulation |
nextUp | ❌ not_relevant | Returns adjacent floating-point value towards positive infinity | low-level IEEE 754 manipulation |
pow | ✅ supported | Returns the value of a raised to the power of b | Follows java.lang.Math.pow's IEEE 754 special-case table, returning :nan / :infinity / :negative_infinity as recoverable signal values instead of raising (e.g. (pow -1 0.5) => NaN, (pow 0 -1) => Inf) |
random | 🔲 candidate | Returns a pseudorandom double between 0.0 and 1.0 | pure (non-deterministic but side-effect free) |
rint | ❌ not_relevant | Returns closest double to argument that is a mathematical integer | use round instead |
round | ✅ supported | Returns the closest long/int to the argument | DIV-43: round-half-away-from-zero, integer result, and special values (NaN/infinity) are preserved rather than Java's floor(x+0.5) and long saturation. DIV-45: integer and BigInt arguments are accepted (returned unchanged) via PTC-Lisp's value model rather than Java's float/double-only overloads |
scalb | ❌ not_relevant | Returns d × 2^scaleFactor | low-level IEEE 754 manipulation |
signum | 🔲 candidate | Returns the signum function of the argument | pure math |
sin | 🔲 candidate | Returns the trigonometric sine of an angle | pure math |
sinh | 🔲 candidate | Returns the hyperbolic sine of a value | pure math |

ulp | ❌ not_relevant | Returns size of an ulp of the argument | low-level IEEE 754 inspection |
