exponent

exponent corresponds to the second component of decodeFloat. exponent 0 = 0 and for finite nonzero x, exponent x = snd (decodeFloat x) + floatDigits x. If x is a finite floating-point number, it is equal in value to significand x * b ^^ exponent x, where b is the floating-point radix. The behaviour is unspecified on infinite or NaN values.

Scientific notation (e.g. 2.3e123).

An exponent is an exponent letter (E, D) and a signed integer.

Display in scientific notation, e.g. 1.234e-5

An exponent.

exponentiating n = iso (**n) (**recip n)

Note: This errors for n = 0

Construct a range which scales the second bound exponentially relative to the size parameter.

>>> bounds 0 $ exponential 1 512
(1,1)

>>> bounds 11 $ exponential 1 512
(1,2)

>>> bounds 22 $ exponential 1 512
(1,4)

>>> bounds 77 $ exponential 1 512
(1,128)

>>> bounds 88 $ exponential 1 512
(1,256)

>>> bounds 99 $ exponential 1 512
(1,512)

Construct a range which is scaled exponentially relative to the size parameter and uses the full range of a data type.

>>> bounds 0 (exponentialBounded :: Range Int8)
(0,0)

>>> bounds 50 (exponentialBounded :: Range Int8)
(-11,11)

>>> bounds 99 (exponentialBounded :: Range Int8)
(-128,127)

Construct a range which scales the second bound exponentially relative to the size parameter. This works the same as exponential, but for floating-point values.

>>> bounds 0 $ exponentialFloat 0 10
(0.0,0.0)

>>> bounds 50 $ exponentialFloat 0 10
(0.0,2.357035250656098)

>>> bounds 99 $ exponentialFloat 0 10
(0.0,10.0)

Construct a range which scales the bounds exponentially relative to the size parameter. This works the same as exponentialFrom, but for floating-point values.

>>> bounds 0 $ exponentialFloatFrom 0 (-10) 20
(0.0,0.0)

>>> bounds 50 $ exponentialFloatFrom 0 (-10) 20
(-2.357035250656098,3.6535836249197002)

>>> bounds 99 $ exponentialFloatFrom x (-10) 20
(-10.0,20.0)

Construct a range which scales the bounds exponentially relative to the size parameter.

>>> bounds 0 $ exponentialFrom 0 (-128) 512
(0,0)

>>> bounds 25 $ exponentialFrom 0 (-128) 512
(-2,4)

>>> bounds 50 $ exponentialFrom 0 (-128) 512
(-11,22)

>>> bounds 75 $ exponentialFrom 0 (-128) 512
(-39,112)

>>> bounds 99 $ exponentialFrom x (-128) 512
(-128,512)
