Details

  • This message is generated when the value of the WorkingPrecision option exceeds the precision of the least precise number in the differential equations.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[NDSolve::precw].

Examples

Basic Examples  (1)

An error is generated because the precision of the machine number in the equations is less than the value of the WorkingPrecision option:

Wolfram Language code: NDSolve[{f'[x] == 1.3 f[x], f[1] == 1}, f, {x, 1, 2}, WorkingPrecision -> 50]

A high-precision result can be computed if the low-precision number in the input is replaced by an exact number:

Wolfram Language code: NDSolve[{f'[x] == (13 / 10) f[x], f[1] == 1}, f, {x, 1, 2}, WorkingPrecision -> 50, PrecisionGoal -> 30]
