ASN.1 REAL type

Limitations

When encoding binary values, only base 2 is supported

Variants

Binary

Fields

mantissa: f64
base: u32
exponent: i32
enc_base: u8

Non-special values

Infinity

Infinity (∞).

NegInfinity

Negative infinity (−∞).

Zero

Zero

Implementations

Create a new REAL from the f64 value.

Create a new binary REAL

Returns true if this value is positive infinity or negative infinity, and false otherwise.

Returns true if this number is not infinite.

Returns the ‘f64’ value of this REAL.

Returned value is a float, and may be infinite.

Returns the ‘f32’ value of this REAL.

This functions casts the result of Real::f64 to a f32, and loses precision.
