InterpolatingFunction::dprec

Details

  • This message is generated when the grid spacing is zero to within the precision of the inputs.
  • This message is generated while computing a value for an InterpolatingFunction expression.
  • This error can occur if the grid spacing is smaller than the uncertainty in the arguments that are passed to the InterpolatingFunction expression.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[InterpolatingFunction::dprec].

Examples

Basic Examples  (1)

The uncertainty in the machine-number argument that is passed to the InterpolatingFunction expression is larger than the width of the interval in which that number falls:

Wolfram Language code: interp = Interpolation[N[{{1, 1}, {1 + 10 ^ -25, 2}, {2, 3}, {3, 4}}, 30]]
Wolfram Language code: interp[1.0]

The interpolation can be computed without difficulty if the argument is a high-precision number or if the argument is exact:

Wolfram Language code: interp[1 + 10 ^ -25 / 2]
Wolfram Language code: interp[1.000000000000000000000000050000]

Clear the value of interp:

Wolfram Language code: Clear[interp]
