121+
#### stdlib_base_complex64_sub( z1, z2 )
122+
123+
Subtracts two single-precision complex floating-point numbers.
124+
125+
```c
126+
#include "stdlib/complex/float32/ctor.h"
127+
#include "stdlib/complex/float32/real.h"
128+
#include "stdlib/complex/float32/imag.h"
129+
130+
stdlib_complex64_t z1 = stdlib_complex64( 5.0f, 3.0f );
131+
stdlib_complex64_t z2 = stdlib_complex64( -2.0f, 1.0f );
132+
stdlib_complex64_t out = stdlib_base_complex64_sub( z1, z2 );
133+
134+
float re = stdlib_complex64_real( out );
135+
// returns 7.0f
136+
137+
float im = stdlib_complex64_imag( out );
138+
// returns 2.0f
139+
```
140+
141+
The function accepts the following arguments:
142+
143+
- **z1**: `[in] stdlib_complex64_t` input value.
144+
- **z2**: `[in] stdlib_complex64_t` input value.
145+
146+
```c
147+
stdlib_complex64_t stdlib_base_complex64_sub( const stdlib_complex64_t z1, const stdlib_complex64_t z2 );
