CReal

Returns the real part of a complex number.

Syntax

CReal( byref z as Complex ) as float64

Notes

• z.re reads the same field. CReal( z ) is the documented spelling because it survives a field rename and because it says at the call site that the operand is complex.
• vector.tiko used to spell this Real. That name is gone with the rest of the mixed scheme — every function in complex.tiko now carries a C prefix, and the complex.tiko section of Math Library says why.

Examples

#import "std/numeric"
using numeric

dim as Complex z = CSet( 3, 4 )

print CReal( z )  '' 3
print CImag( z )  '' 4
print z.re        '' 3   -- the field, same value
