Constructors

finfo(DType)

Create finfo for the specified dtype.

public finfo(DType dtype)

Parameters

dtype DType

A floating point dtype (a Type, NPTypeCode, dtype string or DType — all convert implicitly).

Exceptions

ArgumentException

Thrown if dtype is not a floating point type.

Properties

bits

Number of bits occupied by the type.

public int bits { get; }

Property Value

int

dtype

The NPTypeCode of this floating point type.

public NPTypeCode dtype { get; }

Property Value

NPTypeCode

eps

The difference between 1.0 and the next smallest representable float larger than 1.0.

public double eps { get; }

Property Value

double

epsneg

The difference between 1.0 and the next smallest representable float smaller than 1.0.

public double epsneg { get; }

Property Value

double

max

The largest representable number.

public double max { get; }

Property Value

double

maxexp

The smallest positive power of the base (2) that causes overflow.

public int maxexp { get; }

Property Value

int

min

The smallest representable number (typically -max).

public double min { get; }

Property Value

double

minexp

The most negative power of the base (2) consistent with there being no leading 0s in the mantissa.

public int minexp { get; }

Property Value

int

precision

The approximate number of decimal digits to which this kind of float is precise.

public int precision { get; }

Property Value

int

resolution

The approximate decimal resolution of this type (10^-precision).

public double resolution { get; }

Property Value

double

smallest_normal

The smallest positive normal number.

public double smallest_normal { get; }

Property Value

double

smallest_subnormal

The smallest positive subnormal number.

public double smallest_subnormal { get; }

Property Value

double

tiny

The smallest positive usable number (alias for smallest_normal).

public double tiny { get; }

Property Value

double

Methods

ToString()

Returns a string that represents the current object.
