numpy.seterr — NumPy v1.11 Manual (original) (raw)

all : {‘ignore’, ‘warn’, ‘raise’, ‘call’, ‘print’, ‘log’}, optional

Set treatment for all types of floating-point errors at once:

• ignore: Take no action when the exception occurs.
• warn: Print a RuntimeWarning (via the Python warnings module).
• raise: Raise a FloatingPointError.
• call: Call a function specified using the seterrcall function.
• print: Print a warning directly to stdout.
• log: Record error in a Log object specified by seterrcall.

The default is not to change the current behavior.

divide : {‘ignore’, ‘warn’, ‘raise’, ‘call’, ‘print’, ‘log’}, optional

Treatment for division by zero.

over : {‘ignore’, ‘warn’, ‘raise’, ‘call’, ‘print’, ‘log’}, optional

Treatment for floating-point overflow.

under : {‘ignore’, ‘warn’, ‘raise’, ‘call’, ‘print’, ‘log’}, optional

Treatment for floating-point underflow.

invalid : {‘ignore’, ‘warn’, ‘raise’, ‘call’, ‘print’, ‘log’}, optional

Treatment for invalid floating-point operation.
