JavaScript Math Library Support
All static functions and values defined in the JavaScript Math library may be used. Note that the World Modeler parser does not resolve dot-separated namespaces in qualified names. Calls to Math library functions must be made without any spaces.Math.exp(x) will work but Math . exp(x), although it is legal JavaScript, will not be recognized by
the World Modeler Parser and "Symbol not found" errors will be genrerated.
Supported Math library functions are:
| Math.E | Math.LN10 | Math.LN2 | Math.LOG10E | Math.LOG2E | Math.PI | Math.SQRT1_2 | Math.SQRT2 | |
| Math.abs | Math.acos | Math.acosh | Math.asin | Math.asinh | Math.atan | Math.atan2 | Math.atanh | |
| Math.cbrt | Math.ceil | Math.clz32 | Math.cos | Math.cosh | Math.exp | Math.expm1 | Math.floor | |
| Math.fround | Math.hypot | Math.imul | Math.log | Math.log10 | Math.log1p | Math.log2 | Math.max | |
| Math.min | Math.pow | Math.random | Math.round | Math.sign | Math.sin | Math.sinh | Math.sqrt | |
| Math.tan | Math.tanh | Math.trunc | ||||||
