Modern Math Exp2

Home › Math Library › Math Library › Exp2

Exp2

Returns 2 raised to a power.

Syntax

Exp2( x )

Notes

• The inverse of Log2.
• Overloaded on float64 and on float32: a single-precision argument takes the single-precision path and does not widen.
• BOUNDED accuracy: correct to the platform library's stated ulp bound.

Examples

#import "std/numeric"
using numeric

print Exp2( 10.0 )           '' 1024
print Exp2( 0.5 )            '' 1.414213562373095
print Exp2( -1.0 )           '' 0.5
