exp10()
The
exp10()
is an inbuilt function in
julia which is used to calculate the base 10 exponential of the specified number.
Syntax: exp10(x)
Parameters:
Returns: It returns the calculated base 10 exponential of the specified number.
Example:
println(exp10( 0 ))
println(exp10( 1 ))
println(exp10( 10 ))
println(exp10( - 1 ))
|
Output:
1.0
10.0

exp2()
The
exp2()
is an inbuilt function in
julia which is used to calculate the base 2 exponential of the specified number.
Syntax: exp2(x)
Parameters:
Returns: It returns the calculated base 2 exponential of the specified number.
Example:
println(exp2( 0 ))
println(exp2( 1 ))
println(exp2( 2 ))
println(exp2( - 1 ))
|
Output:
1.0
2.0

0.5
expm1()
The
expm1()
is an inbuilt function in
julia which is used to accurately calculate
.
Syntax: expm1(x)
Parameters:
Returns: It returns the calculated value of .
Example:
println(expm1( 0 ))
println(expm1( 1 ))
println(expm1( 2 ))
println(expm1( - 1 ))
|
Output:
0.0

frexp()
The
frexp()
is an inbuilt function in
julia which is used to return (x, exp), where x is given and having a magnitude in the interval [1/2, 1) or 0.
Syntax: frexp(x)
Parameters:
- x: Specified values in the interval [1/2, 1) or 0.
Returns: It returns (x, exp), where x is given and having a magnitude in the interval [1/2, 1) or 0.
Example:
println(frexp( 0.6 ))
println(frexp( 0.5 ))
println(frexp( 0.7 ))
println(frexp( 0.9999 ))
|
Output:
(0.6, 0)
(0.5, 0)
(0.7, 0)
(0.9999, 0)
